- In general, what is the purpose of washing the red blood cell prior to testing? What are some of the tests that require washing of the red blood cells? What are the important considerations that you have to keep in mind in performing blood typing? Why is FORWARD typing only the screening procedure, not the confirmatory one? Why is REVERSE typing only the confirmatory procedure?What does blood typing detect? A. presence of antigenic substances in the blood sample B. presence of antibodies in the blood sample C. presence of immune-stimulating molecules in the blood anti-sera D. presence of surface feature molecules in the blood anti-seraWhile performing a blood typing assay, the lab technician notes a reaction between the blood sample and the Anti-A serum (A antibodies).
