What does a person do when he has health problems? Runs to take tests! After all, how else to find out what is the source of the problems. Trusting your feelings is not worth it – it can happen that the pain is felt in a completely different place, rather than the affected organ.

Only on the basis of tests the doctor can prescribe a course of treatment. Fortunately, the procedure for donating blood, urine, feces is not painful and inexpensive, but its effectiveness is quite high. But people sometimes refuse to take tests or even do not believe them because of some myths.


If nothing in the body does not bother, then the tests can and do not take.

This is the most common myth that accompanies laboratory diagnostics. But at the same time he is the most dangerous. For example, many oncological diseases can not function for a long time at all. Only consultation with a doctor and carrying out the necessary studies can prevent the disease, detect it at an early stage. No wonder they say – warned, so armed. It is better to detect the disease when it still does not hurt to start fighting it as early as possible. Then the chances of victory will be much higher. And pain can be the last phase of the disease.

Because of the blood test, you can get AIDS.

Modern laboratories use only disposable consumables and equipment. This basically excludes the possibility of contracting HIV. Today it will be difficult to find a laboratory that would use reusable equipment.

A bad doctor will always send for additional analyzes.

Such a myth sooner or later manifests itself before every therapist, regardless of his real skills. It’s just that patients have not yet learned to trust doctors. And it is often additional tests that play a key role in the accurate diagnosis and the appointment of the right treatment. If the doctor asks for additional diagnostics, then it should be considered not as a lack of experience, but as an attempt to better study the patient’s condition, not to be mistaken in the conclusions.

The results of laboratory research are the ultimate truth.

Today, no laboratory can guarantee the accuracy of its results with a 100% probability. Lab technicians are mistaken, factors such as a person’s state of health, his diet, and even the weather, influence him. Of course, the quality of research is constantly improving. But do not panic because of bad results and immediately try to treat them yourself and try to heal. Only a competent specialist on the basis of laboratory diagnosis, the results of other studies can make a correct diagnosis. Probably, it is necessary to retake the analyzes, but maybe their totality will show a completely different picture than it seemed on the basis of a separate study.

If the tests are good, then there is no disease.

Sometimes it happens that the clinical picture is in contradiction with the results of the analyzes. Then you should repeat them. For example, with serological diagnosis of infections in the initial period of the disease, even with a pronounced clinical picture, the analyzes may not show anything.


In fact, laboratory diagnosis is a waste of time.

Some patients believe that the doctor can already diagnose with his external examination. In fact, up to 70% of information about the state of a person is given by tests, allowing you to put the right diagnosis. Laboratory diagnosis allows you not only to properly treat, but also generally to maintain health.

For a future mother, it’s best not to abuse the tests.

There is a point of view that it is better not to burden a pregnant woman with tests, because they harm the unborn yet a baby. This opinion is not only misleading, it is also dangerous. After all, the attending physician can direct the future mother to additional tests, thereby helping to prevent possible complications in the near future.So, donating blood to a blood group can help to avoid Rh-conflict, which is dangerous for its negative consequences. So in this situation, analyzes, on the contrary, only help the woman and her child.

The most accurate analyzes in state polyclinics.

Many of us, out of habit, trust ordinary polyclinics, believing that private medical institutions only think about how to make money. In the 1990s our compatriots found themselves in a rather paradoxical situation. The transition to market relations led to the fact that it was difficult to get qualified medical help, both for free and paid. So then private centers were not particularly effective. Now the situation is gradually improving. State institutions are beginning to receive modern equipment, boasting the use of high technology and private clinics. In addition, high-quality professionals often work there. And in public institutions there was a spectrum of paid services. So that each patient can choose himself calmly, where and how it is better to be examined and treated. Someone principally uses the services of private institutions, and someone is more pleasant than polyclinics. Nevertheless, it should be remembered that in order to obtain a full dynamic picture, analyzes should be made in the same laboratory, on the same equipment and using the same reagents. This is the only way to see the development of processes.

Analyzes should be taken in the morning and on an empty stomach.

This rule is not always correct. If it is a clinical blood test, then it is better to skip breakfast. Analyzes for sex hormones (FSH, LH, etc.) should really be given at the beginning of the day and on an empty stomach. But the blood for the study of glycosylated hemoglobin or serological diagnosis of infections are taken during the day after a couple of hours after eating. A PCR study of scrapings on urogenital studies generally do not have any time or food intake restrictions. In any case, the requirements for the delivery of the analysis should be clarified in advance.


The results of laboratory research remain constant throughout the year.

In fact, the results are influenced by many things. This is the daily routine of a person, his emotional and physical condition, diet. That’s why the indicators can jump not only during the year, but even a week or even a day.
