If your white blood cell count was low on your blood screening, there are a full range of possibilities. Are you sick? Then that is why. If you are fighting illness, and not being successful (getting sicker) then your white cell count would be low. If you have a low white blood cell count even when you get a cold or the flu or some other less severe sickness, and you start to get better, then it is possible that you have HIV. HIV results in the lowering of white blood cells. There are also certain medications that lower the white blood cell count. If you want more help, message me!
The percentage of lymphocytes is not really important. The percentage can be low either due to fewer lymphocytes or do to an increase in other cells.
If the absolute lymphocyte count (ALC - the white blood cell count x the % lymphocytes) is low that can mean that there is a problem with the immune system although mildly low levels are usually nothing to worry about.
Type your answer here... may be in neutrophilia, acute bactarial coditions
Your white blood cell count is low!
Dr Been will tell
it is an indication of bacterial infection
In general, chronic stress is known to lower the function of the immune system, and that would include reducing the lymphocyte count.

White Blood Cell count less than 500 places the patient at risk for a fatal infection.
The term "lymphocyte" can be translated to "white blood cell"--lymphocytes are just one of a few different types of white blood cells in the body. The normal lymphocyte count for an adult is between 1000 and 4800 cells per microliter; lymphocytopenia is a lymphocyte count lower than the norm. Lymphocytes are important to the human immune system, so a low lymphocyte count may mean you're more vulnerable to infection or other problems.
A low neutrophil count along with a high lymphocyte count can be an indication of viral infections, autoimmune diseases and leukemias. That might rule out valley fever.
This would depend upon the what is causing the high lymphocyte count and which lymphocyte is elevated. For serious questions involving actual cases, you need to ask your physician.
Mildly low WBC counts are usually the result of low-grade viral infections. Even the common cold (rhinovirus) can precipitate mildly low WBC counts. (Also, on the differential, the lymphocyte portion of the WBC count is often somewhat elevated.)
viral infection
If you mean lymphocyte, as a percent of total white cells the normal range for adults is 18-40%. 21% is toward the low end but falls within the normal range.
I just tested positive for Lyme disease with similar high lymph count and low WBC. You may want to get tested for Lyme which can cause an array of problems but one of the most common being joint pain.
