Based on saliva inhibition test results, what is the secretor status? Saliva + Anti-A + A cells: +; Saliva + Anti-B + B cells: +; Saliva + Anti-H + H cells: +.

Secretor status is decided by whether ABH substances are present in saliva. In a saliva inhibition test, these soluble ABH substances in secretions will block the binding of anti-A, anti-B, and anti-H antibodies to their corresponding red cells, leading to no clumping (inhibition) when the saliva is mixed with the antisera and the specific cells. Here, there is clumping with anti-A and A cells, with anti-B and B cells, and with anti-H and H cells. That lack of inhibition means the saliva did not contain ABH substances to neutralize the antibodies. So the individual does not secrete ABH antigens in saliva, which defines non-secretor status.
