Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 29F. Low wbc and neutropenia. Referred to hematology. Stressed because it takes time to see specialistI just need some peace of mind, something that can calm me down my pcp called me after my cbc test and said that they want to refer me to Hematologist just to make sure they dont miss anything. The soonest appointment for hematologist is in the end of January! I dont know what to do because all I can think of is Cancer or HIV because what else can explain my low wbc 2.9k/UL (3.9-12 standard range) and neutrophils 34.8% (40-70%) high lymphocytes 52.4% (25-45%) and high basophil 2.1 (0-2%) I am absolutely terrified and cant wait that long to find out whats causing it Can PCP run other tests in a mean time?. ### Response: What else could cause it? A viral illness. Nutritional deficiencies. Drug induced neutropenia. Benign ethnic neutropenia. There's many potential causes besides what you jumped to. There are some tests your doctor could do, like a peripheral blood smear, folate and B12, some liver function testing and some screening panels depending on clinical suspicion from history and exam. Many of these may have been done or deemed not necessary..
