Instructions on how to read blood test results

During the examination, doctors still often appoint patients to do blood tests and urine tests. But if the doctor does not explain, we also cannot understand what the indicators on the test results mean. So we should know how to read the results of blood or urine tests when going to a health examination. Please follow the article below to learn how to read the blood test results.

I. How ingredients of blood formula

1. WBC (White Blood Cell - Number of white blood cells in a blood volume)

The value is usually in the range of 4,300 to 10,800 cells / mm ³ , equivalent to the number of leukocytes in international units of 4.3 to 10.8 x 109 cells / l.

Increased in infection, malignant blood disease, leukemia . decreased in aplastic anemia, deficiency of vitamin B12 or folate, infection .

The value is usually between 4,300 and 10,800 cells / mm3.

2. RBC (Red Blood Cell - Number of red blood cells (or erythrocyte count) in a blood volume)

Values ​​are usually between 4.2 and 5.9 million cells / cm ³ , equivalent to the number of erythrocytes in international units of 4.2 to 5.9 x 1012 cells / l.

Increased in dehydration, erythrocytosis; decrease in anemia.

3. HB or HBG (Hemoglobin - Amount of hemoglobin in a blood volume)

Hemoglobin is a type of protein molecule in red blood cells that carries oxygen and produces red blood cells.

Values ​​vary by gender, usually between 13 and 18 g / dl for men and 12 to 16 g / dl for women (8.1 to 11.2 millimole / l, respectively, and 7.4 - 9.9 millimole / l).

Increased in dehydration, heart disease and lung disease; decrease in anemia, bleeding and reactions that cause hemolysis.

4. HCT (Hematocrit - Ratio of erythrocyte volume on total blood volume)

Value varies by gender, usually between 45 and 52% for men and 37 to 48% for women.

Increased in allergic disorders, erythrocytosis, smoking, chronic obstructive pulmonary disease, coronary artery disease, in the mountains, dehydration, hyperventilation; reduction in blood loss, anemia, pregnancy.

5. MCV (Mean corpuscular volume - Average volume of a red blood cell)

This value is taken from HCT and the number of red blood cells. Normal values ​​range from 80 to 100 femtoliter (1 femtoliter = 1/1 million liters).

Increased in vitamin B12 deficiency, folic acid deficiency, liver disease, alcoholism, erythrocytosis, hypothyroidism, bone marrow aplasia, bone marrow fibrosis; reduction in iron deficiency, thalassemia syndrome and other hemoglobin diseases, anemia in chronic diseases, anemia of erythrocytes, chronic renal failure, and lead poisoning.

6. MCH (Mean Corpuscular Hemoglobin - The average number of pigmented blood in a red blood cell)

This value is calculated by measuring hemoglobin and the number of red blood cells. Normal values ​​range from 27 to 32 picograms.

7. MCHC (Mean Corpuscular Hemoglobin Concentration - Average concentration of hemoglobin in a blood volume)

This value is calculated by measuring the value of hemoglobin and hematocrit. Normal values ​​range from 32 to 36%.
In sharp anemia: normal red blood cells, severe hereditary circular erythrocytes, the presence of cold agglutination factors.

In renewable anemia: may be normal or decrease due to reduced folate or vitamin B12, cirrhosis, alcoholism.

8. PLT (Platelet Count - Platelet Count in a blood volume)

1. Platelets are not a complete cell, but fragments of cytoplasm (a cell component that does not contain the nucleus or stem of the cell) from cells found in the bone marrow.
2. Platelets play a vital role in blood clotting, with an average life expectancy of 5 to 9 days.
3. Values ​​usually range from 150,000 to 400,000 / cm ³ (equivalent to 150 - 400 x 109 / l).
4. Too low platelet counts will cause blood loss. Too high platelet counts will form blood clots, interfere with blood vessels, leading to stroke, myocardial infarction, pulmonary embolism, blood vessel blockage .
5. Increased in bone marrow proliferation disorders, idiopathic thrombocytopenia, bone marrow fibrosis, post-bleeding, after splenectomy . leads to inflammatory diseases.
6. Reduction in bone marrow suppression or replacement, chemotherapy, splenic hypertrophy, scattered intravascular coagulation, platelet antibodies, purpura after blood transfusion, and thrombocytopenia due to homogenization Infant.

Lymphocyte helps the body fight infections.

9. LYM (Lymphocyte - Lymphocytes)

Lymphocyte helps the body fight infections. There are many causes to reduce lymphocytes such as reducing immunity, HIV / AIDS, TB, malaria, blood cancer, lymphoma .

Normal values ​​range from 20 to 25%.

10. MXD (Mixed Cell Count - rate of cell mixing in blood)

Each type of cell has a certain percentage of blood. MXD varies depending on the increase or decrease in the ratio of each cell type.

11. NEUT (Neutrophil - The rate of neutrophils)

Normal values ​​range from 60 to 66%. High incidence indicates blood infection.

Increased in acute infection, acute myocardial infarction, stress, cancer, myeloid leukemia; reduction in viral infection, aplastic anemia, immunosuppressive drugs, radiation therapy .

12. RDW (Red Cell Distribution Width - Degree of erythrocyte distribution)

This higher value means that the distribution of red blood cells changes more and more. Normal values ​​range from 11 to 15%.

Normal RDW and:

1. MCV increases, encountered in: aplastic anemia, before leukemia.
2. MCV is normal, encountered in: anemia in chronic diseases, blood loss or acute hemolysis, enzyme disease or anemia without anemia.
3. MCV reduced: anemia in chronic diseases, heterozygous thalassemia

RDW increases and:

1. MCV increases: vitamin B12 deficiency, folate deficiency, immune hemolytic anemia, cold agglutination, chronic lymphocytic leukemia.
2. Normal MCV: early iron deficiency, early stage vitamin B12 deficiency, early folate deficiency, anemia caused by globin disease.
3. MCV reduction: iron deficiency, red cell fragmentation, HbH, thalassemia.

13. PDW (Platelet Disrabution Width - The platelet Disrabution Width)

Normal values ​​range from 6 to 18%.

Increase in lung cancer, sickle cell disease, gram positive, gram-negative sepsis; Reduce in alcoholism.

14. MPV (Mean Platelet Volume - The average volume of platelets in a blood volume)

Normal values ​​range from 6.5 to 11fL.

Increased in cardiovascular disease, diabetes, smoking, stress, poisoning by thyroid .; reduction in anemia due to aplasia, massive erythrocyte anemia, cancer chemotherapy, leukocytosis .

15. P-LCR (Platelet Larger Cell Ratio - Large platelet size)

GLUCOSE is blood sugar.The normal limit is from 4.1 to 6.1 mnol / l.

1. GLU (GLUCOSE) - Blood sugar

The normal limit is from 4.1 to 6.1 mnol / l. If the limit is exceeded, increase or decrease blood sugar. Above the limit is a person at high risk for diabetes.

2. SGOT & SGPT: Liver enzyme group

The normal limit is from 9.0-48.0 with SGOT and 5.0-49.0 with SGPT. If this limit is exceeded, the hepatotoxicity of hepatocellular cells decreases. Limit food and drink intake to make it difficult for liver to absorb and affect liver function such as animal fat and alcohol and carbonated drinks.

3. MOTHER BLOOD group

Includes CHOLESTEROL, TRYGLYCERID, HDL-CHOLES, LDL-CHLES

The normal limit of these group elements is as follows:

1. Normal limits range from 3.4-5.4 mmol / l with CHOLESTEROL.
2. Normal limits range from 0.4-2,3 mmol / l with TRYGLYCERID.
3. Normal limits range from 0.9-2.1 mmol / l with HDL-Choles.
4. Normal limits range from 0.0-2.9 mmol / l with LDL-Choles.

If one of the above factors exceeds the permitted limit, there is a high risk of cardiovascular disease and blood pressure. Particularly HDL-Choles is good fat, if high it limits blood vessels. If the CHOLESTEROL is too high with high blood pressure and high LDL-Choles, the risk of stroke and stroke is very high. Avoid eating foods high in fat and cholesterol such as animal viscera, poultry eggs, shrimp, crabs, beef, chicken skin . Enhancing sports. Drink more garlic alcohol and monitor blood pressure regularly.

4. GGT: Gama globutamin, is an immune factor for liver cells

Normally, if liver function is good, GGT will be very low in the blood (From 0-53 U / L). When liver cells have to work excessively, the ability of liver to be toxic is reduced, the GGT will increase -> Reduce the resistance and immunity of liver cells. Easy to lead to hepatic cell failure. If people with SVB in the blood that GGT, SGOT & SGPT have increased, it is necessary to use liver cell supplements and absolutely do not drink alcohol or the risk of hepatitis B is very high.

5. URE (Blood urea)

The most important degradation product of protein is excreted by the kidneys.

Normal limit: 2.5 - 7.5 mmol / l.

6. BUN (Blood Urea Nitrogen)

BUN = urea (mg) x 28/60; Unit conversion: mmol / lx 6 = mg / dl.

1. Increased in: kidney disease, high protein intake, fever, infection, urinary obstruction .
2. Reduce in: low protein intake, severe liver disease, depletion .

BUN: is the nitrogen of urea in the blood.

Normal limit 4.6 - 23.3 mg / dl. -> Bun = mmol / lx 6 x 28/60 = mmol / lx 2.8 (mg / dl).

1. Increase in: kidney failure, heart failure, high protein intake, fever, infection .
2. Reduce in: eating less protein, severe liver disease .

7. CRE (Creatinine)

CRE is a product of excretion of muscle creatin phosphate degradation, the amount of muscle mass depends on the muscle mass, is filtered through glomerular & urine; also the most stable protein component regardless of diet -> has a value for determining glomerular function.

Normal limit: male 62 - 120, female 53 - 100 (unit: umol / l).

1. Increase in: kidney disease, heart failure, diabetes, idiopathic hypertension, acute MI .

URIC is a metabolite of purine base (Adenin, Guanin) of DNA & RNA, mainly discharged through urine.

Normal limit: male 180 - 420, female 150 - 360 (unit: umol / l).

Increase in:

1. Originally: due to increased production, due to reduction (spontaneous) -> related enzymes: Lesh Nyhan disease, Von Gierke .
2. Secondary: due to increased production (myeloma, psoriasis .), due to reduced excretion (kidney failure, medication use, atherosclerosis .).
3. Gout (gout): hyperuricemia / blood may be accompanied by tophi nodules in the joint & kidney urate stones.

Reduction in: Wilson's disease, hepatocellular injury .

9. Immune results
