Most people who go to the doctor get a blood test to detect many other dangerous diseases. If you do not know how to read specific blood test results, you can follow the information below of Ngonaz. This makes it easier for people to take the initiative in situations.
What is a blood test?
Blood test is a process of examining and analyzing the composition, properties and functions of a blood sample to assess health status and diagnose disease. With blood tests, important parameters and indicators are measured and evaluated, including:
Red blood cell count: A blood test to determine the number of red blood cells in a blood sample. Abnormal red blood cell counts can indicate problems such as anemia, blood disorders, or other medical conditions.
White blood cell count: A blood test can measure the number of white blood cells, including types of white blood cells such as total white blood cells, lymphocytes, and granulocytes. An abnormal white blood cell count can be a sign of infection, inflammation, or other conditions.
White blood cell analysis: A blood test that analyzes the percentage of different types of white blood cells and evaluates the immune function of the body’s system.
Platelet count and percentage: A blood test that measures the number and percentage of platelets, an important measure of kidney function.
Hemoglobin levels: A blood test can measure the amount of hemoglobin, a substance found in red blood cells that helps transport oxygen throughout the body. Abnormal hemoglobin levels can be a sign of anemia.
Coagulation time: A blood test that measures blood clotting time to check how well the blood clotting system is working.
Chemical indicators: Blood tests can also measure chemical indicators such as blood sugar, cholesterol, liver function, kidney function, etc. to assess overall health.
The most accurate way to read blood test results
For the most accurate blood test results, pay attention to the following units and indicators:
Glu (sugar): blood sugar
| Glue (glucose) | The reference range is 4.1 – 5.9 mmol/l. |
In this way, there will be 2 situations:
– If it exceeds the allowable reference threshold: you have hypoglycemia.
– If the reference range is exceeded: this means you are at risk of diabetes or impaired glucose tolerance/metabolism.
SGOT & SGPT: Group of Liver Enzymes
| SGOT & SGPT: Group of Liver Enzymes | The normal range of SGOT is 9.0 to 48.0 and the normal range of SGPT is 5.0 to 49.0. |
As you know, the liver has an important function in detoxifying the organs in the body. When receiving the result, there will be 2 possibilities:
If the liver enzyme index is elevated, it may be a sign of liver cell damage due to inflammation, fibrosis, cancer, etc.
If the enzyme index decreases, it can be a warning sign of diabetes, pregnancy, edema …
When this limit is exceeded, liver function is impaired. Therefore, it is necessary to control foods, drinks, alcohol … that the liver is not easily absorbed.
Lipid group: cholesterol, triglycerides, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C)
| – Blood cholesterol reference range < 5.2 mmol/l (adults) and < 4.4.2 mmol/l (children). |
| The reference range for blood triglycerides is <1.7 mmol/l. |
| Reference range for HDL-cholesterol 1.03 – 1.55 mmol/l |
| The reference range for LDL cholesterol is 3.4 mmol/L |
When you get results outside of the above reference range, you have a higher risk of heart disease and high blood pressure.
HDL cholesterol test: Thought to reflect cholesterol transfer from atherosclerosis.
– Pass the LDL cholesterol test: Reflects bad cholesterol, because LDL cholesterol increases massively in the blood, causing it to be deposited on the walls of blood vessels, causing plaque. This can lead to life-threatening conditions like heart attack, stroke, etc.
GGT: gamma glutamyl transferase
| GGT: gamma glutamyl transferase | Reference range of GGT in blood: 0-55 U/L. |
GGT is an enzyme that metabolizes amino acids and regulates glutathione levels in the body. It is also the first enzyme to be affected when there is damage to the liver and biliary tract. When the GGT test helps rule out certain liver and gallbladder disorders.
Urea (blood urea)
| Urea (blood urea) | The reference range for blood urea is: 2.5 – 7.5 mmol/l. |
Urea is synthesized by the liver in the tricarboxylic acid cycle and is the most important product of nitrogen metabolism. Blood urea concentration depends on 3 factors: renal function, electrolyte balance and endogenous protein catabolism.
BUN (blood urea nitrogen) is the nitrogen fraction of urea with a reference range of 8 – 24 mg/dL equivalent to 2.86 – 8.57 mmol/L (male) and 6 – 21 mg/dL equivalent to 2.14 – 7.50 mmol/L female .
Cre (creatine)
| Cre (creatine) | Serum creatinine reference range:
Male 74 – 120, female 53 – 100 (umol/l). |
Cre is a waste product of phosphocreatine degradation in muscle, the amount formed depends on muscle mass and this substance is returned to the circulation. In the kidney, Cre is filtered through the glomerulus, not reabsorbed by the renal tubules and excreted in the urine. Therefore, the Cre component is the most stable protein component independent of the diet and reflects the patient’s renal function.
– If blood Cre is elevated as above: It is easy to cause kidney disease, heart failure, diabetes, …
– If blood Cre is reduced: pregnant women, eclampsia, malnutrition…
uric acid (uric acid)
| uric acid (uric acid) | Serum uric acid reference range:
Male 180 – 420, female 150 – 360 (umol/l). |
Uric acid is a metabolic product of purine nucleic acid base, mainly excreted in the urine, a small amount is excreted in the gastrointestinal tract.
– If blood uric acid is high: It can warn of diseases such as obesity, edema, psoriasis, kidney failure.
– If blood uric acid decreases: It can warn of diseases such as Wilson’s disease, antidiuretic hormone secretion syndrome, Falconi syndrome.
immune results
Anti-HBs . Test
Anti-HBs test checks the body’s immunity to hepatitis virus and determines hepatitis B virus antibody levels. Your attention:
- If you have received the hepatitis B vaccine or have been infected with the hepatitis B virus and recovered, your body will make antibodies against the hepatitis B virus and you will have a positive anti-HBs test result.
- If hepatitis B antibodies are strong (100-1000 IU/ml), no prophylaxis is needed. But if the antibody is weak (0-10 UI/ml), then there is a high chance that you have hepatitis B.
– HBsAg
HBsAg is the surface antigen of the B virus and the results will tell you if you have the B virus. The reference range for this blood test is negative.

Be careful when testing blood
– Prepare psychologically before blood test.
– If you feel dizzy after drawing blood, tell your doctor or laboratory staff immediately for help.
– After the examination there is usually a small bruise due to the puncture of the needle. However, then it fades away.
So you know how to read specific blood test results. Hopefully this information can help people understand their health status, plan a reasonable diet and exercise.
