CD34 (Precursor Cell Marker)

The Precursor Cell Marker test, commonly called the CD34 panel test, determines the level of CD34 marker in your blood. The test can be prescribed to check your viability as a bone marrow donor. The CD34 is an important antigen that features heavily during bone marrow transformations.

Usually, the CD34 panel test is done in combination with other tests to confirm whether your Human Leukocyte Antigens (HLAs) markers are a good match with that of the recipient. The HLAs are proteins, or markers, found on most cells in the human body. Through these markers, the immune system can recognise which cells belong to your body and which do not. In the end, if the donor’s HLA is similar to the recipient’s, the latter’s immune system will not reject the bone marrow.

Furthermore, the CD34 test is helpful in assessing the overall health of your immune system. You may be asked to undergo a CD34 panel test if you experience any of the following symptoms:

• Fatigue
• Dizziness
• Dry Mouth
• Chills
• Cramps
• Joint Pain

If these symptoms persist for more than a few days, they may indicate a medical issue. In this case, it is advisable to consult your physician. You physician will likely recommend a Precursor Cell Marker test to gauge your immune system’s health.

The procedure for the CD34 test is similar to that of a standard blood test. So, this test does not require any special preparation. But it is advisable to inform your doctor about any medications you take so that they can determine if the same will impact your test results.

During the CD34 test, the phlebotomist (person drawing the blood) uses a needle to draw blood from the vein in your arm, usually at the bend of the elbow. This blood is carefully collected in a tube and further sent for analysis.

You should note that the Precursor Cell Marker test is an early screening and diagnostic test through which doctors cannot make a definite conclusion. If the count of CD34 cells in your body is low, it may indicate some serious health complications. The doctor may suggest some additional tests as a follow-up to ascertain the underlying health issue.
