How to decipher a blood test
Donate blood for analysis Not once had to every person. This is one of the important methods of laboratory research, appointed in most diseases, because changes in the composition of the blood reflect the processes occurring in our body.
as Blood of a healthy person By its cellular composition is quite constant, changes in it, occurring as a result of various diseases, are immediately visible.
So that the test is most accurate, the blood should be taken on an empty stomach or at least 2 hours after eating. For repeated analyzes Blood sampling Spend at the same time and under the same conditions.
How to decipher a blood test
When deciphering the results of the analysis, literateThe doctor will necessarily take into account the sex of the person and his physiological state. For example, in women pms increases soy and decreases the number of platelets.
Only the doctor will be able to accurately read the analysis, but knowing the indicators of the norm and looking at your analysis, you can have an idea of what is happening in your body processes.
- Hemoglobin (hb)
Complex protein, the main component of erythrocytes, the main function of which is the transfer of oxygen from the lungs to the tissues and the excretion of co2.
Normal indicators: For men - 130-160 g / liter, for women - 120-140 g / liter. If hemoglobin is lowered, this indicates possible anemia or hemorrhage, and much higher rates indicate dehydration, blood diseases and certain types of heart failure.
This is the blood corpuscles that contain hemoglobin. Normal values for men - (4,0-5,1) ⋅ 10 in the 12th degree of cells per liter, and in women - (3,7-4,7) ⋅ 10 in the 12th degree of cells per liter.
In healthy people, excess red blood cells can be observed at high altitude in the mountains. But usually this indicates a possible disease of the bronchi, lungs, kidneys, liver, heart.
Excess steroid hormones also affects thisindex. The lack of red blood cells speaks about anemia, acute blood loss, chronic inflammatory processes. Sometimes manifested in late pregnancy.
These are white blood cells, they are produced in the bone marrow and Lymph nodes To protect the body from toxins, viruses, bacteria, dying own cells.
(4,0-9,0) ⋅ 10 in the 9th degree of cells per liter -Norm for all. Excess speaks of inflammation or bacterial infection in the body. It happens that the level of leukocytes "jumps" as a result of severe stress, physical strain or pregnancy.
Viral infection, as well as taking analgesics and anticonvulsants lead to a decrease in the number of leukocytes.
Cells responsible for blood clotting. Normal number for all - (180-320) ⋅ 10 in the 9th degree of cells per liter. An increased number may indicate tuberculosis, ulcerative colitis, cirrhosis of the liver.
Decrease in platelet count occurs atAlcohol consumption, poisoning with heavy metals, blood diseases, kidney failure, liver disease, spleen, hormonal disorders. Some drugs (antibiotics, diuretics, digoxin, nitroglycerin) also reduce the blood platelet count.
- Soy, or roe
Sedimentation rate of erythrocytes in a test tube. The norm for men is 2-10 mm / h, for women it is 2-15 mm / h. This is an important indicator of the course of the disease or general condition.
High values are observed in infections,Inflammations, anemia, kidney disease, hormonal disorders, shock after injuries and surgeries, during pregnancy, after childbirth, during menstruation. And reduced - in case of circulatory failure, anaphylactic shock.
The value of soy in women is always slightly higher than that of men. The change in the protein composition of the blood during pregnancy also leads to an increase in soy.
Normal for all indicators Blood glucose level - 3.5-6.5 mmol / liter. The concentration below these values indicates an irregular diet, hormonal failures. A high indicator indicates diabetes mellitus.
- Total protein
The norm is 60-80 g / liter. Decreases after severe diets, as well as in violations of the liver and kidneys.
- Common bilirubin
Bilirubin - the indicator of liver function. The norm is 20.5 mmol / liter. With hepatitis, cholelithiasis or erythrocyte destruction this indicator increases.
An index of 0.18 mmol / liter indicates normal functioning of the kidneys. The excess of this figure indicates a kidney failure.
Take care of your health and remember that the body always signals us on time! And it's pointless to diagnose to oneself without precise analyzes.
