Hematology Lab Tests
Complete blood count and lymphocyte subsets are the most commonly used hematology lab tests to monitor HIV infection. Below is a brief account of the two:
Lymphocyte Subsets is one of the hematology lab tests that touch on the percentages of CD4 and CD8.
CD4 is known as the helper T- cell count. Calculating it is most probably the most essential medium utilized to assess the total condition of the immune system in persons who are diagnosed with HIV. It operates in transmitting signal to other immune system cells to combat a detected virus in the body. Between 500 to 1, 500 cells per cubic millimeter is the normal CD4 tally. When the person does not undergo a treatment, about 50 to 100 cells per cubic millimeter each year is the average for a person with HIV infection. Infections such as Pnuemocystis pneumonia typically appears when the helper T-cell count is below 200.
CD8 is called as the suppressor T- cell. It plays a very vital role in battling with viral infections such as HIV. A count between 150 to 1, 000 cells per cubic millimeter is the usual for a healthy adult. Ironic to CD4 cells, those who are diagnosed with HIV mostly have high results of CD8 cells. Hematology lab results may also suggest that the T- cell ratio, which is the number of CD4 cells divided by the CD8 cells. Due to the fact that CD4 is always lesser and the CD8 higher than normal, the ratio is mostly low in those who have HIV infection.
Complete Blood Count is one of the hematology lab tests that taps on red blood cells, platelets and white blood cells.
Red blood cells, also known as erythrocytes, function in supplying oxygen all over the human body. In a single cubic millimeter of blood, there are about 3.6 to 6.1 million erythrocytes. A decreased number of red blood cells is called anemia. It is brought about by certain anti- HIV drugs or a sign of an underlying sickness.
Platelets are the elements in the blood that are responsible for clotting. It is also called as thrombocytes where the normal count of which is between 150, 000 to 440, 000 per cubic millimeter of blood. Some of those who have HIV and have low platelet count is called thrombocytopenia.
White blood cells, also known as luekocytes, work as protection against any manner of infection. It has several classes and sub- classes under it where they form in the bone marrow. In an average, a well- conditioned person a count of 4, 000 to 11, 000 luekocytes per cubic microliter of blood. When having hematology lab tests, it will show high white blood cell count that indicates a virus seen in the body. If there is a low white blood count, it suggests that a particular illness or medication has damaged the bone marrow's capability of generating new cells.
