What does low WBC count indicate?
hello and thank you for sending the question.
This is one of the most common consultations received by hematologists. I do see that your white blood cell count is trending lower but this does not necessarily mean that there is any type of life-threatening hematological disorder going on.
many many things can contribute to lowering of white blood cell count including medications, vitamin deficiency, autoimmune phenomenon and sometimes there can be a problem with in the bone marrow which can disturb the production of active amounts of white blood cells. It does appear that you have an adequate immune system at this time. And at this time I do not see any signs of danger.
I think it is reasonable for you to review your case with a hematologist. The hematologist might request some additional laboratory testing which may include eight per referral blood smear.
The blood smear will allow a physician or pathologist to study your blood cells under the microscope to see if there is any abnormality or irregularity which might help delineate the cause of the low white blood cell count.
Sometimes we never find a major cause and we end up having to just follow the blood count over a long period of time.
on many occasions continued monitoring of the blood count will reveal a mild fluctuation up and down. Other considerations include viruses but if you are otherwise feeling well I would tend to think that this might be something which the hematologist will recommend following over a period of time.
Additional testing such as a bone marrow biopsy is not necessarily indicated unless you have a Nino or low platelet count.
Thanks again for sending your question. Please let me know if you have any additional specific concerns that you would be interested in reviewing
Thnak you for your response its very much appreciated. I will tell you that my vitamin D was low...its was 28. My Dr put me on 8 week vitamin D suppliment. Its been a tough winter here in CT..havent been outside much. Can this attribute to the low count? Also, i do take Lorazepam for anxiety only when needed.. I did take it a few times last week. I see after looking it up that this too can cause a decrease in WBC but its rare? I will attach the last page of my blood work for you too see.
thank you for the additional information.
It is remotely possible that lorazepam could contribute to this but I have never seen it and it would be considered very rare.
I think again that it is reasonable to check the blood count again in a couple of months. Also it is important that the peripheral smear be examined for any abnormalities. The computer and machine can tell us things about the blood count but actual visualization of the blood cells is important.
I suppose it is possible that the vitamin D issue may be related but this is not likely. I think it would be reasonable for you to visit with a local hematologist for a comprehensive evaluation but this is not something that is urgent. At some point within the next few months it would be reasonable especially if the count remains slightly below average.
Thanks again for visiting with us. Sincerely,
