Interpret the following microcytotoxicity results: A9 and B12 cells damaged; A1 and Aw19 cells intact.

Interpret the following microcytotoxicity results: A9 and B12 cells damaged; A1 and Aw19 cells intact.

• A. Positive for A1 and Aw19; negative for A9 and B12
• B. Negative for A1 and Aw19; positive for A9 and B12
• C. Error in test system; retest
• D. Impossible to determine

Answer: (B)

The interpretation of the microcytotoxicity results involves analyzing which cells were damaged versus those that remained intact. In this case, the A9 and B12 cells were damaged, indicating that these cells are positive for the test being conducted, which typically reflects an antibody-mediated response or compatibility. Conversely, since the A1 and Aw19 cells are intact, this signifies that there was no damaging interaction or response affecting these cells, indicating that they are negative for the test. Therefore, the correct interpretation is that A1 and Aw19 are negative, while A9 and B12 are positive based on the results of the experiment. This aligns with the provided answer, which correctly reflects the positive and negative classifications of the cells based on their states post-testing.
