What conditions disqualify a patient from testing?

Blood samples of patients with hematological malignancies may contain cells with abnormal variants, which may affect testing sensitivity and specificity. In this case, buccal swabs are recommended, but there may still be residual effects.

Additionally, if a patient has received an allogeneic bone marrow or stem cell transplant, neither blood nor buccal swab samples are eligible for testing.
