Medical questions: what you need to know about taking the test, and why take the blood from the ring finger?

For sure, every person at least once thought - why take blood from an anonymous finger? And not from the middle or, for example, large. Well, this question is quite clear.

Expert opinion

Clearer and more objective only the doctor can tell. And that's what doctors say. Blood is the same everywhere, but it is customary to take it from an anonymous finger for analysis, because a puncture that involves damage to the integrity of the skin is fraught with infection. Of course, not always, but anything can happen. So, the inner shell of the little finger and the thumb have a specificity - they are directly connected to the one that belongs to the brush. And if the infection is in them, then its spread to the whole hand is assured.

That's why they take blood from the ring finger. Its shell is isolated. And even if the infection gets there, it will be localized. And this makes it possible to quickly suppress it and avoid unpleasant consequences.

However, there is another answer to the question of why the blood is taken from the ring finger. It is believed that the blood vessels located in it, go directly to our main organ - the heart. Therefore, they try to take blood from it (although it is still permissible to use the index and average). And the reason is very clear. After all, cardiac activity is the basis of the whole blood circulation.

Practical approach

This is not all the reasons why they take blood from an unnamed finger. The second, no less important, lies in its minimal working capacity. But in fact, where is the ring finger used? When a person writes, he is not involved. When typing on the computer - too (except for journalists who use all the fingers). In domestic situations, it is also not required: when you get money, cut bread, dial SMS on your phone, etc.

This means that the skin on the ring finger is the thinnest. And the puncture, respectively, is not so painful. And this finger moves less than others, which contributes to the early healing of the wound and reduces the likelihood of infection.

Does the hand matter?

This is also an interesting question. Many are interested in - why take blood from the ring finger of the left hand? It's simple. Because most patients are right-handed. And, consequently, their right hand is constantly involved in the performance of a particular case. And that after the procedure it was as convenient and painless to perform something, the doctors use the finger of the left hand.

But! If a person is a left-handed person, everything is exactly the opposite. And he needs to warn the doctor about it - ask him to take the blood from the finger of his right hand. As already mentioned at the outset, our biological connective fluid is the same everywhere. So the approach to the procedure in this case is of a purely practical nature.

What should I consider when I pass the analysis?

So, why take the blood from the ring finger - clearly. Now it is worthwhile to list the factors that a person should warn a doctor before he takes analysis from him. And that's what the patient has to say:

• Whether he is engaged in sports;
• Is subject to sharp physical stresses that run counter to the usual sedentary lifestyle;
• Whether the medication was taken within 2 weeks before blood donation (because even the usual pain medication or sleeping pills could distort the results of medical research);
• Whether he is a vegetarian;
• Whether there are chronic diseases;
• Whether he has carious teeth.

All these nuances will be taken into account when deciphering the analysis. Girls are even encouraged to clarify information about their monthly natural processes. As the composition of the blood affects every process that takes place in the body - even the one that seems insignificant.

Interesting Facts

So, what factors need to warn the doctor and why they take blood for analysis from the ring finger - clearly. Finally, it is worth paying attention to an interesting topic, namely, the features of the ring finger.

At the beginning of the article it was said that he is the most motionless. And this finger is usually used together with the rest - for grasping. Why? Because the fingers unite their common tendons. Anonymous can be used separately, except in the case of playing musical instruments. And with professional typing.

It was also said above that the vessels from the ring finger lead directly to the heart. And the Egyptians and Romans, among other things, it was considered not so much a physiological feature as a reason for a special purpose. In their own interpretation of this specificity, they began to wear engagement rings on nameless fingers. What is practiced to this day.

Finally I would like to say that the fourth finger is not "named" in all languages. Most often it is called "ring" or "finger". In English, for example, it sounds like "ring finger".
