Low WBC count and high monocyte count

[sixstring08]

Hi Doctor,

I had my annual physical exam and the result of my CBC revealed a WBC count of 3.8 x 10e9/L and a monocyte count of 0.14 (normal range says it should be 0.02- 0.08 only). All other WBC components are within normal range including neutrophil and lymphocyte. All other hematology results are also within normal range. I have had unprotected sex before and am concerned about contracting HIV. Should I be concerned with my CBC results? I've read that a low WBC and high monocyte count could either be because of chronic infections such as TB, HIV, etc. or could be due to an autoimmune disease.

Looking forward to your response.

Thanks.

Thanks so much Sir. I am planning to have a repeat determination of my CBC to see if the results are worth further evaluation. I am also planning to have an HIV test to know my status.

Thanks again.

Your WBC count is only slightly low; most people with WBC 3,800/mm3 (equivalent to your 3.8 result) have nothing wrong. And your monocyte count is normal. Percent count is technically high, but 0.14 x 3800 = 532/mm3, which is in the high normal range. If your counts are consistently in this range, comprehensive medical evaluation would be recommended. Such results could occur in HIV, but that's an exceedingly unlikely reason, even if you are at hih risk for it. As for autoimmune diseases or other problems, that's something to discuss with your doctor if he or she recommends further evaluation.

If you remain concerned about HIV, forget blood countes and just have an HIV test.
