B Cell Count Test

South Dakota rates for HCPCS 86355

This blood test counts the number of B cells, a type of white blood cell responsible for producing antibodies. It helps evaluate how well a person's immune system is functioning, particularly when there's concern about an immune deficiency or an unexplained pattern of infections. Low counts can point toward a problem with antibody production, while other patterns can help guide further immune testing.
