Result Interpretation

• Negative (Safe): Two distinct red lines appear — one in the Control region (C) and one in the Test region (T). Sildenafil level is below the detection limit.

• Positive (Detected): Only one red line appears in the Control region (C); no line appears in the Test region (T). Sildenafil meets or exceeds the detection threshold.

• Invalid: No line appears in the Control region (C). Discard and retest with a new cassette.
