What is LDH analysis

What is LDH analysis

This analysis is a test for the presence of an enzyme known as lactate. This enzyme is found in most cells of the body and is not found in the blood in large quantities. This enzyme is present in large quantities in the blood when the cells of the body are seen as an indicator of a defect, Or destruction of the content of these cells. This enzyme is in the form of five isotopes in different parts of the body such as the heart, erythrocytes, kidneys and lungs, liver and muscle, leukocytes and lymph nodes. These isotopes are present in one part of the body such as the heart, kidneys and liver. These areotopes are released into the blood and the damage to the cells can be determined by determining the type of these isotopes.

Reasons for conducting this examination

  • This examination is required from the patient when suspected of abnormal cell development, and the desire to know the causes of the defect and control the level of this enzyme, where the enzyme LDH high in this case.
  • If the level of this enzyme is high, the patient is required several tests for the isotopes of this enzyme to determine the location of imbalance in the cells of the body.
  • This test is used to diagnose anemia caused by the breakdown of blood cells.
  • Heart attack symptoms, which gives an indication of the condition of the heart and blood vessels.
  • Cancer, especially lymphoma.
  • Liver and kidney diseases, and pancreatitis.

Method of collecting blood samples

Blood samples are collected through the syringe and the results are not different whether blood or venous or arterial, and must follow the health precautions in the process of blood withdrawal, because non-compliance with these things lead to the transfer of various diseases,

Save samples and collect them

  • Chilled blood samples are kept to prevent changes in blood components, and preservatives can be added to keep samples longer.
  • Samples can be kept frozen for longer use.
  • Collect samples in the morning, so that the patient is fasting.
  • Ensure the cleanliness of the tubes where the blood is collected.
  • Maintain the temperature of the sample until it is transferred to the laboratory.

When this enzyme rises naturally

We can find through laboratory tests that the level of LDH high without the existence of a clear problem in the body in the following cases:

  • Exercising in a stressful manner increases the level of this enzyme.
  • Analysis of the blood sample during the test procedure due to non-handling of the sample correctly, inappropriate storage conditions and high sample temperature lead to incorrect high values.
  • If the platelet level is high in the patient, the concentration of this enzyme is high.
