Lymphocyte Subset CD4 Test

Lymphocytes are a particular type of white blood cells that are present in the blood composition and have specific functions related to fight against diseases and provide immunity to the body. The white blood cells have a unique feature in the body and are an important part of the immune system. When a patient is ill or when the patient has a weak immune system, this implies that the patient lacks sufficient white blood cells in their bloodstream. The lymphatic system is a key part of the body that is helpful to produce the lymphocytes into the blood. These lymphocytes are generally produced by the bone marrow at a constant rate and the produced lymphocytes enter the bloodstream through the lymphatic system.

The Lymphatic Subset CD4 tests have multiple methods and these results imply in a number of diseases. The proportion and ratio of lymphocytes in the white blood cells give the disease’s features. The patient has to be informed in prior about the test and also should be informed about results and their implications. The Catalyst of varied and different colors should be maintained in prior to having a quick transport of the sample to the actual test area. Pink (K2EDTA), Lavender (EDTA), or green (sodium or lithium heparin) Hemogard tubes need to be preferred for laboratory automation and safety.

The lymphocytes basically consist of a combination of B Cells, T Cells, and NK Cells. These test when shows deficiency of a particular lymphocyte type, helps the doctor to classify the disease of the patient. The severe diseases like the Human immune Virus are also confirmed only through the lymphocyte CD4 test. Based on the age, gender, heritage of the patient and some other factors the results may confirm traits like HIV, pregnancy, recent infection, steroid therapy, high stress, etc.

Generally, the CD4 lymphocyte test requires 4 ml of the pureblood sample. For this, a broad needle is pierced into the patient’s artery initially and the blood is extracted. The extracted blood is transferred to a Hemogard tube which is then shipped to the test area. The pierced area of the patient’s body should be neatly rinsed and cleaned with pure alcohol/spirit. A nominal temperature should be maintained while collecting the sample and while testing the sample a cold temperature place is preferred.
