Today I want to share an interesting topic that mixes what fingerprinting1 is with a very recurring topic in medicine, such as the measurement of capillary blood glucose. It seems that these These topics have nothing to do with each other, but there is something important that I want to highlight in this publication, something that I particularly emphasize to people who use a glucometer and that usually goes unnoticed.
1 is the science that deals with the identification of fingerprints.
As an interesting fact, each person has a fingerprint that identifies them, this is completed in the 19th week of gestation, where it already becomes fixed and unique for each human being.
The first recorded studies of this science (fingerprinting) date back to the 19th century, but it did not have a great impact at that time, it was not until 1891 when it was used for the first time to solve a crime and began to be used in a global.
I make this introduction because it is important to know that our fingerprints are unique, no two are alike, which has made it to be used as the main global identification system, and also as an important aspect to be considered, and from this moment on I hope that whoever reads this publication, will handle the information to guide people who know and use glucometer constantly.
The glucometer is an instrument used to measure blood glucose levels in people. It is usually used daily by people with diabetes. At least twice a day. And it is not precisely the use of this that I want to highlight but a necessary part in the process of use.
To use it you must make a small puncture in the thumb of one finger, with a needle that is on the tip of what looks like a pencil, with the intention of obtaining a drop of blood, which will be placed on a slide that is connected to the glucometer, and after a few seconds you will get the value of blood glucose of the person.
This allows to have a very easy control of how the glycemia values are being managed so that the doctor knows if a readjustment of the treatment has to be made or not.
So far everything seems normal, it is a common and easy procedure to perform, it does not really require a special preparation for it, however, there is a common mistake that is made when performing it and this is what I want to emphasize. And it is the moment in which I relate the first thing I talked about in this publication (dactyloscopy) with this second one, the use of the glucometer.
The images I used above I have obtained from Pixabay, a free image bank, but if you look for images to illustrate the process you will see that they are all similar, and the vast majority indicate the process and make the same mistake.
A person using the glucometer will have to polish their fingers several times a day, each small injury with the needle, over time will leave a tiny scar, but if we look at it in the long term will be many scars that may end up altering the fingerprint.
The issue here is that it is not only that alteration that originates in the fingerprint, which is our main form of identification, but that our fingers have a high sensitivity especially in the thumbs of these, it is there where we have more nerve endings temperature receptors, tactile and pain, therefore, it is extremely painful to press where most do, although they end up adapting is not logical.
Then I can say that the purpose is to obtain a small drop of blood for the test with the glucometer, and to avoid the pain in addition to the alteration of the fingerprints with the constant injury with the needle, it is advisable to do it in the sides of the finger(As I show in the image above) and not in the center, since this way the pain is much less, and also the fingerprint is not altered.
I wanted to share this information that I think is important, since it is a very common mistake that I usually see. Considering also that current phones use fingerprints as a form of identification and thus allow us access to our phone, and many other uses that we give to our fingerprint, and that every time technology will make us make more use of this unique feature in humans.
As I said at the beginning of the publication, the intention was to leave in you an important knowledge so that you can somehow help those people who deserve it with this information that can help them to have less suffering by inflicting less pain, in addition to preserving their natural identification tool, their fingerprint.
