Description

The clinical test for lactate dehydrogenase (LDH) is a laboratory test used to measure the amount of LDH in a patient's serum. LDH is an enzyme found in many tissues and organs, and its levels can be used to diagnose certain diseases and conditions.

To obtain a sample of serum for the LDH test, a healthcare provider will draw a sample of blood from the patient's arm. The sample is then sent to a laboratory for analysis. In the laboratory, the serum is separated from the other components of the blood and tested for LDH levels. The results of the test are then reported back to the healthcare provider.
