I just read an interesting article on concerning testing blood glucose levels by using TEARS rather than blood. The article is based on a report published in the American Chemical Society journal Analytical Chemistry. An abstract of the report and the full report can be read at

The following is from the article-

“Scientists are reporting development and successful laboratory testing of an electrochemical sensor device that has the potential to measure blood sugar levels from tears instead of blood… “

"Thus, it may be possible to measure tear glucose levels multiple times per day to monitor blood glucose changes without the potential pain from the repeated invasive blood drawing method," say the researchers.

The following is from the ACS abstract-

“The glucose sensor was employed to measure tear glucose levels in anesthetized rabbits over an 8 h period while also measuring the blood glucose values. A strong correlation between tear and blood glucose levels was found, suggesting that measurement of tear glucose is a potential noninvasive substitute for blood glucose measurements, and the new sensor configuration could aid in conducting further research in this direction.”

It may not be tomorrow when we need not test from blood but there is a light at the end of the tunnel. I know my poor fingers are cheering. In fact I thought I heard a few hallelujahs and amens. How do your fingers feel about this alternate type of testing?

I don't think that tears are as accurate as blood. Besides, how is one going to get tears to check their glucose? By poking themselves in the eye every time they need to check their #s? I'm all for the old fashioned way. I've been doing it for the past 16 years (roughly: 116,80 sticks) since I was diagnosed in April of '95. So my fingers have not only become numb to the stick, it's also has become quite painless. But it's very interesting that they are working on a way for people who find the pokes, stabs, sticks annoying or painful might be a thing of their past. I hope that it will happen in the very near future for people young and old.

at this point in my life I don't feel much in my fingers due to nuraphty. I have it some what bad between my hands and feet and I really don't want any more pain in my hands. Or my feet come to think of it. As it is I have to have another surgery on my right foot. This cold weather lately don't help none. Who is worried about a tiny pin prick.

At the stage of the game, what's another few hundred stix? My fingers have turned to callus any way. It's even hard 4 me 2 squeeze any sizable amt of blood for a test. I have run outta fingers. Say, can I use my toes? lol :>

stormz 2011-12-06 20:29:00 -0600 Report

I'm not going there. I already said I have to have surgery on one foot why would I use my toe? I'm in way too much pain in my feet as it have me opting out for not testing at all.

2011-12-07 12:46:40 -0600 Report

I wouldn't suggest that to you stormz. You're already in WAY to much pain, I'm sorry to say. I am so sorry that you are in that much pain. I've heard that there is a way to check your b/s on your arm. But then I hope that's at least 1 part of your body that isn't full of pain. It really is exhausting to always be in such excruciating pain. Wish there was something that I could do for you.

stormz 2011-12-07 14:03:25 -0600 Report

LOL Not doing it on my arms either I had uhmm 3 surgeries on one arm and 2 on the other either way we go I'm not testing on my arms either. I give up there. I think I am going for my other way I am opting out for not testing at all at this point. Maybe I will go back to testing once I am done sticking myself every day for my osteo only 9 months to go for that. That was a 2 year project. Your right when you say I am in a lot of pain. Just putting on shoes that are fitted for me is painful. To think I am a happy person still. Loving life because I know I still have a lot to live for. Only thing anyone can do for me is pray. God Bless

Young1s 2011-12-07 14:44:03 -0600 Report

I hope you don't really go 9 months without testing but given what you just described, I don't blame you for not wanting to. I will pray for you to get some relief in order to keep the testing up. Be blessed.

stormz 2011-12-07 18:26:14 -0600 Report

thanks I'll prolly test I'm not really going to go that long without testing please that would be insane besides I can't feel it really I just am tired of being stuck is all. God Bless

stormz 2011-12-07 14:57:30 -0600 Report

thanks but really what would it hurt if I didn't test? I know what the symptoms are if my sugar is too low or high and what to do so what am I hurting..I have been a diabetic long enough to know. I have it fully under control. Between being on a diet and meds am I really doing something so bad that I will loose control of it all?

Young1s 2011-12-07 15:03:45 -0600 Report

I don't know, are you? And if you don't test how will YOU know? One or two seconds of minor pain, a few times a day, would be nothing compared to the pain you described above. Not trying to tell you how to handle your D, only you know your body, just would hate for something to happen to you, that could have been avoided if you were fully on top of things, is all.

if only i would have known i would have saved all the tears i cried OVER my diabetes in the past i would have kept them FOR my diabetes in the future!!

catdogcj 2011-12-02 21:16:08 -0600 Report

Sounds interesting but how would that work. Are you supposed to make yourself cry all the time?

Uncle Lew 2011-12-03 10:20:12 -0600 Report

It would not be too hard to cry with tears of joy when you think about how much money you are saving by not having to buy test strips and lancets. I am in tears already.

lifedriver 2011-12-06 09:56:52 -0600 Report

LOL Me Too

Young1s 2011-12-06 15:54:25 -0600 Report

I think you misunderstood. They are referring to the posibilities of not having to stick themselves, based on the what Uncle Lew posted in the discussion topic.

You know this is the season for Hallmark commercials! Yes, Yes, Yes, I tear up at Hallmark commercials. This could work during the holiday season…

Mickey/CCHT 2011-12-04 21:05:28 -0600 Report

Hey! I cry at those too! And some songs will do that to me! The day we signed up to sponsor our little guy in brazil, I was listening to the song "Love Song for a Savior" by Jars of Clay and crying all the way down the expressway! Yes, they were tears of joy and being full of the Holy Spirit, but I was still crying!!

jayabee52 2011-12-02 12:58:25 -0600 Report

Now that I'm older I and have been through a lot of life and heartache I find myself doing that too. I never did that as a young man.

stormz 2011-12-02 13:02:47 -0600 Report

I'm with you jaybee52 I don't feel much of nothing either in my fingers that is. Not going to mention nothing about my head LOL

2011-12-06 16:46:16 -0600 Report

Yes, I even cry at those Hallmark commercials too!! Like the solider who is stationed overseas and gets one of those books U can record 1s voice w//. It gets me every time. To the point where I sent my fiance' a recordable card 4 a just because {I love you} (He is stationed in/& fighting in Afghanistan.) So those commercials do get to the old heart strings.

Caroltoo 2011-12-06 17:43:44 -0600 Report

Those old commercials sure do get to many of us, me too! Wishing you and your fiance a good Christmas and hoping his tour is completed soon.

stormz 2011-12-02 17:40:17 -0600 Report

Why remember old times when you have better things to look forward to. I try to forget what my husband said to be only because he was so degrading and I am not as bad as the things he use to say to me. I doubt you are either. :) God Bless!

jayabee52 2011-12-02 17:54:17 -0600 Report

I remember the good and the bad and use what I have gone through to learn from it and if what I have gone through helps someone else it was worth it to go through it. And certain things just "trigger" a memory and I can't shut it off.

Actually what she said was somewhat amusing to me, even though some would say it was a bit abusive: She would say "where there is no sense (pointing to the head) there's no feeling".

No if your husband was an abuser (even if only verbally) You are NOT what he said you are! Probably felt he needed to beat you down so he could feel better about himself and perhaps control you.

stormz 2011-12-02 18:36:07 -0600 Report

Oh your 100% right about him and controlling me. I ended up packing my things and leaving as soon as I could. Like you if what happened to me could help someone I'm glad it was me that went through it because I am a strong person. A meek person he would have killed. Your also right we can't just shut off our memories as much as I like to at times. Your lucky that you can laugh at some of the things she said to you. There was no humor in what was done to me. But I am still better off now. I am a better person because of it all. I am more secure. God helps those who help them selves. God Bless!

jayabee52 2011-12-02 18:39:59 -0600 Report

And I've found that God's word is true and God helps those who rely on HIM to get them through the toughest and scariest times of our lives.

So very true. He has gotten me through the worst of times and the best of times and I thank him every day for being there for me.

Just saw on the TV news a report about a CONTACT LENS that will be able to measure blood glucose levels. No details yet but I am investigating. No more finger sticks and no more whacking yourself with a hammer or a 2x4 for tears.

catdogcj 2011-12-02 21:18:22 -0600 Report

Nice thought, but not everyone wears contacts.

jayabee52 2011-12-02 21:50:08 -0600 Report

well just because your eyes don't need correctlon doesn't mean you couldn't wear them. I don't wear contacts eiither but if I could read my BGs that way I would find a way to do it.

Caroltoo 2011-12-01 11:50:24 -0600 Report

Uncle Lew: contact lenses that can read BG … amazing thought. I can just see it, walking down the street after lunch at the spaghetti house, getting a BG high, and having your eyes starting to flash red. :) Just kidding, of course, but it makes a funny visual. On a more serious note, I'm really amazed and glad to see the innovations that are beginning to come our way.

Uncle Lew
Uncle Lew 2011-12-02 16:04:33 -0600 Report

You are not too far off. The original lenses have gradations of green is for normal, red for extremely low glucose and violet for extremely high glucose. This for now. Researchers are trying to use nano-technology to develop displays like the eyes in the Terminator.

catdogcj 2011-12-02 21:24:27 -0600 Report

Thats what I'm saying. I wouldn't want to see flashing colored lights in front of me all the time. It would be pretty annoying.

Caroltoo 2011-12-02 23:15:08 -0600 Report

Sure did … Dr. Tim and all those folks. I was in UC at the time all that was happening. Very interesting time to be in the University.

jayabee52 2011-12-02 23:22:20 -0600 Report

quite interesting. I went to college in 1973 to 77 in small religious colleges in Ann Arbor MI and Ft Wayne IN. Not much drugs that I saw there. I'm sure they were there, but not so openly like they they were in other non religious universities.

Caroltoo 2011-12-02 23:53:25 -0600 Report

True: they were a little more discrete with the psychedelics, but mj was so common you'd smell it as you walked down the corridor. Good learning experience though. Some years later when I walked in the cooler of my 7-Eleven franchise I recognized it right away. Told the clerk I felt like I'd get high just being in there and he needed to quit smoking in the cooler and on the job. A few days later I found a bong behind the magazines and realized he had a more serious problem. Major bummer, he was a very reliable night clerk. :(

Its the wave of the future. Eventually we will all be part human, part machine and part computer. I wonder what machine oil (WD 40) and crunching data will do to blood glucose levels.

Yes, the breakthroughs of modern technology are miraculous. We are in a new age. Our grandchildren won’t believe we had to prick our fingers to get blood for testing. They will really believe we lived in the stone age.

Caroltoo 2011-12-01 17:29:21 -0600 Report

Considering just 100 years ago diabetes was a death sentence, we are awfully close to the diabetic stone age.

Mickey/CCHT 2011-11-30 19:52:42 -0600 Report

Sounds interesting. What I want to know, is how you get to your tears? If i have to whack myself with a hammer to cry, I will stick with the poke! LOL All joking aside, I would really like to know. The finger pokes are not too bad, my lancet needle is SO tiny, but if I didn't have to poke, I would really think that would be cool!
Thanks for sharing!
Blessings, Mickey

jayabee52 2011-11-30 20:17:48 -0600 Report

I think you'd have to whack your digits with a mallet to get a tear. Ouch!

Mickey/CCHT 2011-11-30 20:55:05 -0600 Report

I know, right!! I refuse to whack myself with anything. As klutzy as i am, I need to do anything on purpose!! Do you know I fell off of one of our stools at work the other day!! No joke! Was waiting for a pt to rinse back. I noticed some of the gauze fell on the floor, so i bent over to pick it up. Well the stool was a little too high, so it shot out from underneath me and i fell right to my butt on the floor, in front of all the pt's!!
It's ok to laugh, I would too! I just laid on the floor for aminute and just said Good Grief, like charlie brown!! HA. I was not hurt(considering how fluffy I am, I have no extra fluff in the bum dept!), but i was really embarresed!!

Young1s 2011-11-30 19:58:26 -0600 Report

Mickey, are you saying that there are different thicknesses in lancet needles like that are in insulin needles. If so, I am definitely getting a thinner size. Because my lancets hurt, whereas I barely feel my insulin needles. And because I stick at least 6 times a day, my fingers peel on occassion. Very unsightly.

watson4042 2011-12-02 13:20:22 -0600 Report

hey guys, remember i'm new and my stuff is the onetouch delica. the lancets are a 33 gauge. i'm a big sissy-la-la when it comes to poking myself. my kit came with a lancet pen to poke yourself with which has a dial for depth of pokes. works great and i have no problem using it.

Mickey/CCHT 2011-11-30 20:19:21 -0600 Report

Oh hecks ya! When I picked out a meter, one of the reasons i bought the one i did, is because it stated it had one of the smallest diameter lancet needles. When i saw it, i was amazed! It is so thin you can barly see it. I know you can buy the lancet itself without having to get the meter also. The meter is the OneTouch Mini Ultra. I was even sent a 20 coupon for one, but i already own it. If you want the coupon, I will send it too you, just email me your address(promise not to stalk you!!) But really, you don't have to if you don't want, it's not a biggie. Either way, check into it, I barely can feel the poke. Sometimes not even at all! Sometimes I think it miss fires until i squeeze my finger and there is blood!! Good luck! :)

BD manufactures lancets in both 30 and 31 gauge (there are no thinner on the markey yet) that fit virtually all lancet devices. I use the 32 gauge lancets in a Bayer Contour device.

Uncle Lew
Uncle Lew 2011-12-02 06:49:36 -0600 Report

BD stands for Becton, Dickinson and Company. They manufacturer syringes, needles for pens, lancets and many other items. I use their 30 gauge lancets and their Nano needles on my insulin pen. The Nano needles are 32 gauge and only 4 mm long. With these needles you do not need to pinch your skin when injecting insulin. Since you do not have to pinch you can inject in the buttocks and back of the arm as well as the thigh and abdomen without help. Their website is which describes their products and has a lot of illustrated information on the proper injection of insulin.

Young1s 2011-11-30 20:34:56 -0600 Report

Woww… I am all over this. Wish I had known about these sooner, could have saved myself some pain. Including the first time I stuck myself…without the cap on. Yeah OUCH!! I never did that again. Also, I always wondered why the finger sticks at my docs office were far less painful than when I do it. I finally just chocked it up to them being more experienced at doing it. Live and learn.

Hold on to that coupon. I am fortunate enough to have insurance with very affordable co-pays, but maybe someone else here can use it. Be blessed.

Caroltoo 2011-11-30 20:22:39 -0600 Report

Thats what I use also. Seldom hurts. If you don't get enough sample, you can adjust for more depth. I keep mine at about 5.
