Hello my 10 year old son is again having a bout of severe fatigue with abdomen pain. lymphs 1.0, 21%, neutrophils 66%, what could the low lymph mean?

Abd pain: Lymphocytes usually have an inverse relationship with neutrophils. The higher the neutrophils the lower the lymphocytes. Lymphocytes generally get higher with viral infections and neutrophils higher with viral infections. Fatigue is common with any malady. Common medical practice for kids with new onset abd pain is an ultrasound for appendicitis and /or repeated daily examinations. CBC, UA, BMP
