This analysis is a test for the presence of an enzyme known as lactate dehydrogenase, this enzyme is present in most cells of the body and is not found in the blood in large quantities, and this enzyme is present in large quantities in the blood when the body cells are fired as an indication of a defect in what is in them, such as the occurrence of abnormal developments within the cells Or the destruction of the content of these cells. This enzyme is present in the form of five isotopes in different parts of the body such as the heart, red blood cells, kidneys and lungs, liver and muscles, leukocytes and lymph nodes. These isotopes are found in any part of the body such as the heart, kidneys and liver, and these isotopes are released into the blood. The site of damage to cells can be determined by determining the type of these isotopes.

The reasons for this examination
- This examination is requested from the patient upon suspicion of non-normal development of cells, and the desire to know the causes of the defect and monitor the level of this enzyme, as the LDH enzyme is elevated in this case.
- If the level of this enzyme is elevated, the patient is required to conduct several isotope tests to determine the location of the defect in the body's cells.
- This test is used to diagnose hemolytic anemia.
- Symptoms of a heart attack, as this examination gives an indication of the condition of the heart and blood vessels.
- Cancer, especially lymphoma.
- Liver and kidney disease, and pancreatitis.
Method of collecting blood samples
Blood samples are collected through the syringe, and the results do not differ, whether the blood is venous or arterial, and health precautions must be followed in the process of drawing blood, because failure to adhere to these matters leads to the transmission of various diseases,
Preservation and collection of samples
- Blood samples are kept refrigerated to prevent changing blood components, and a preservative can be added to preserve samples for a longer time.
- Samples can be kept frozen for longer use.
- Samples are collected in the morning, so that the patient is fasting.
- Ensure the cleanliness of the tubes in which the blood collects.
- Maintain the temperature of the sample until it is transferred to the laboratory.
When does this enzyme rise naturally
We can find through laboratory tests that the level of LDH is high without there being a clear problem in the body in the following cases:
- Exercising in a stressful manner increases the level of this enzyme.
- Analyzing the blood sample during the test as a result of not handling the sample properly, improper storage conditions and high sample temperature lead to incorrect high values.
- If the patient has an elevated platelet level, then the concentration of this enzyme is high.
