The test results may be interpreted once the control line(s) have formed and the background on the test strip(s) has cleared. This will occur in approximately three (3) to five (5) minutes. The test results are determined by the presence or absence of the test and control lines; therefore color blindness will not affect reading the results of the test. The test results are stable for up to four (4) hours.

Test Valid

The control line is the uppermost line appearing in each test channel. Before reading the test result lines, verify that the control line has formed in each test channel, indicating that the test is valid. If the control line does not appear in each test channel, the test is INVALID and the test results must not be used. The test should be repeated using a new Rapid TOX Cup II device. The intensity of the control lines may vary.

Any line, without regard to intensity, color or size, is a line!

Test Invalid

If no control line appears after approximately ten (10) minutes, consider the test invalid.

Repeat the test using another Rapid TOX Cup II device.

Negative

A NEGATIVE result for a single drug in a multiple assay test strip is the presence of a reddish-purple line adjacent to the drug name. A negative result for single assay test is the presence of two reddish-purple lines, the upper control line and the lower test line. The intensity of test lines may vary.

Any line, without regard to intensity or size, is a line and should be considered as a negative result.

Preliminary Positive

A PRELIMINARY POSTIVE result for a single drug in a multiple assay test strip is absence of a line adjacent to the drug name. A preliminary positive result for a single assay test strip is the presence of only one reddish-purple line (the control line) and NO test line.
