A lymph blood test is used to measure the levels of lymphocytes, a type of white blood cell, in the bloodstream. This test helps in evaluating the immune system's function and can be used to diagnose infections, autoimmune disorders, and certain types of cancer.
Usually, it is used to check for infection.
it means lymphopenia
A low lymph level on a blood test may mean several things. If the level is only a little low a viral infection could cause the low, if the low lymph persists, further testing should be done to rule out cancer and problems with the spleen.
A simple blood test will be performed to see if a person has a low level of lymphocytes. Low lymph levels can lead to anemia and susceptibility to other diseases.
it is observed in acute stage of infections, and in excess irradiation.
Lymph comes from the interstitial fluids spaces in blood where interstitial fluid is found. Lymph is composed mainly of white blood cells.
Serum is in the blood vessels (circulating blood). Lymph is the plasma that diffuses through the arteries (used to be part of the blood) into the lymph system. Once it flows through the lymph system, it will rejoin with blood through veins.
Lymph is basically the same as the plasma from the blood. Lymph is formed when plasma leaks out of blood vessels into the interstitial space.
