Substance N-telopeptide
This substance is formed as a result of bone tissue breakdown. Its level can be detected by bringing urine or blood to the laboratory for analysis. For the analysis to be more accurate, urine should be taken daily.
You can detect from this analysis how quickly new bone tissue is created and how quickly old bone tissue is destroyed. If the second indicator (bone tissue breakdown) is higher than the first (creation of new bone tissue), then the N-telopeptide level will be more than 35 units.
If the rates of destruction of old bone tissue and creation of new tissue are the same, then the N-telopeptide substance will be less than 35 units.
But if the HT level is much higher than 35 units, it means that the bones are being actively destroyed. And even if they look healthy and strong, the process of their destruction has already begun and the bones will soon become brittle. This means that you may have frequent fractures that are difficult to heal.
What to do to keep bones strong?
First, you need to stop the process of bone tissue destruction. To do this, you need to actively take calcium as recommended by your doctor (excess is also bad).
But to strengthen bones, you need constant active but feasible sports activities. Morning exercises lasting 15 minutes every morning will be a good gift to your body. It will be able to more actively build up and compact bone tissue.
There are also methods for strengthening bones. This is hormone replacement therapy. Such drugs as Fosamax, Astonel, Miacalcin will help your body reduce the level of HT and bring it to normal.
What will a general blood test tell you?
This test is an indicator of whether the level of blood cells, which determine the quality of the blood, is high or low. If the indicator is too low, then you may suffer from anemia (this is especially true for pregnant women). Or a person may have leukemia - a terrible blood disease that is very difficult to treat.
To avoid the active course of these diseases, you need to do a general blood test at least once a year.
Hematocrit and hemoglobin tests
How many of these or those blood cells are in the body, and what their sizes are, can be determined using tests for the following blood substances.
- Hemoglobin
- Erythrocytes
- Hematocrit
Their average amounts will enable the doctor to determine the concentration of these substances in the body, their level and range of distribution throughout the body.
For women and men these are different indicators, so you should ask your doctor about the norms.
Remember one thing: the level of these substances is significantly lower than 38 units – this is an indicator of the development of anemia. For both men and women.
Leukocyte analysis
These blood cells play an important role in the body. They help a person resist infection and strengthen the immune system. What is included in the leukocyte group?
- Granulocytes
- Monocytes
- Lymphocytes
For each of them, the body has different norms. But it is important for you to know: if one or another group is much larger than the indicators of the other two (up to 90% of the total number of cells), then this is a malfunction in the body.
Neutrophils - their level is too high - up to 80% - only when you have an infection in your body. A virus can raise this level incredibly high - up to 90% and even higher. Then the level of monocytes and lymphocytes also rises.
If the level of these substances is slightly higher than normal, it is not scary. It will normalize as soon as you establish your work and rest regime.
Normally, you should have 4.5 – 10.6x103 blood cells.
Platelet analysis
These blood cells control the blood clotting process. How quickly or slowly the blood clots depends on them. If the platelets are much lower than normal - up to 100,000, or more than 500,000, this means that the body is experiencing abnormal hematopoiesis and blood flow processes.
Antigen analysis
There are special substances in the body – antigens, which determine whether tumors will form and grow in different parts of the body.

Cancer antigen PA 125
This antigen becomes abundant when a woman has ovarian cancer or fibrosis. Its level can also be high when an ovarian cyst or uterine fibrosis develops. Endometriosis or adenomatosis can also cause an increase in the level of the antigen called PA 125. Or early pregnancy.
Such an antibody test is also done for those who suffer from obesity. Because the presence of this substance is almost always an indicator of the development of a benign or, worse, malignant tumor.
An analysis for this antibody is essential for those who have a genetic predisposition to cancer, that is, those whose close relatives have suffered from it.
If the symptoms are unclear, that is, a person experiences uncomfortable and incomprehensible sensations or even pain in the abdomen, lower abdomen, stomach or intestines, an antibody test is also necessary to track what disease a person is prone to.

Iron level test
This analysis is necessary to check the heart function and the tendency to cardiovascular diseases. The norm of iron in the body is 50-90 units, which are measured in ng/ml.
If there is more iron in the body than normal, this may indicate a tendency to heart and vascular diseases.
Iron levels over 200 units may be a sign of hemochromatosis. This is a genetic disorder in which a person has elevated iron levels in their blood. Such a high level may also indicate that you are abusing iron-containing medications. Then additional tests are needed to determine the cause of the elevated iron level – supplements or bad heredity.
When the iron level reaches more than 150 units, this is a signal of poor functioning of not only the heart, but also the kidneys, muscles, and even the brain. For men, this may mean decreased libido and weak erection. For women, it is a tendency to diabetes.
If iron is more than 125 units, this is not a very high indicator, but still high enough to stop taking vitamin complexes with iron. To reduce the level of iron in the blood, it is enough to donate blood several times (if there are no contraindications).
If your iron levels are normal, you can simply support your body by taking vitamins containing iron.
If the iron is below normal - that is, less than 40 units - you may suffer from insomnia, muscle fatigue, especially in the leg muscles, cramps, and increased fatigue.
Hair loss may also occur in excess of the permissible limits (when hair remains in clumps on the comb or there is a lot of it on the pillow or clothes).
To increase your iron levels, it is important to consult your doctor about taking vitamin complexes containing iron. You should take them before you develop anemia.
The period of taking these supplements is not so short - from six months to 9 months. The period of taking these drugs depends on when the iron level steadily reaches the norm - from 50 to 90 units.

What urine, saliva and hair tests can tell you
By doing these tests, you will know the exact picture of whether you have a hormonal imbalance in your body. Many sources claim this, offering you to pay for these tests. In fact, this is not true. Hormonal imbalance may not be calculated from these results.
This is proven by studies in which doctors compared saliva and blood tests of the same person over the course of 24 hours. It turned out that blood and urine tests showed such different results that an accurate picture of the hormonal balance in the body was not obtained.
What to look for in a blood test?
It happens that all hormones in the body are within normal limits. But still, health is not in order, and this is signaled, first of all, by weight. It increases, then decreases. A person cannot control his weight, without understanding the reason.
So, the average norm of hormones in the body can differ significantly from your personal norm, at which you will be healthy or sick. In particular, the following indicators may differ
- Normal production of hormones by the ovaries: estradiol or testosterone
- The normal production of thyroid hormones, such as thyroid hormone
These indicators may be higher or lower than medical standards, but for you they are normal. This means that, having found slightly elevated indicators of certain hormones, the doctor must first find out how you feel about it.
If it is good, no treatment is required. If it affects your well-being, additional tests are needed.
