What does it mean when your RBC are high?

What low WBC, RBC, high Lymph mean?

• I just had a blood test. The blood test show low WBC (3.7), RBC (3.87) and high Lymph (50.2%). Meanwhile I got a urine test. The urine test show high WBC (73) and high leukocyte esterase 3+. What the results tell me? My doctor left me a phone message said that my test result is normal. But it is not normal from my point of view. I appreciate if anyone could tell me what the possible reason may be for this and what I should do about it. I had taken radiation contrast when I went through a CT scan several years ago. I am worried this is cancer related symptom. With thanks in advance. From: Lucy

• Answer:

  The low WBC is normal The RBC count is likewise normal. The high %age of Lymphs is ACTUALLY within the normal range given the low WBC. The number of Lymphs would be somewhere like 1.8 - pretty normal. The WBC in the urine and the Leucocyte Esterase suggest a urinary tract infection. This might be all that is wrong with you at present. I wonder if your doctor is sending the urine for culture and sensitivities.
