PERFORMANCE CHARACTERISTICS
1. Analytical Sensitivity. The Acro Rapid Methamphetamine Urine Test detects methamphetamine and its metabolites in urine at concentrations
equal to or greater than 500 ng/mL. Please see the "cutoff study" and method comparison" section for details.
2. Analytical Specificity. Interference of substances that may be present in urine specimens, as well as effect of sample pH and specific gravity
was also studied.
a. Cross-reactivity of non-methamphetamine related compounds were tested using the assay devices. No cross-reactivity was detected with the
substances listed in Table I.
b. Table II lists Methamphetamine related substances and concentrations that produced results approximately equivalent to the cutoff level for
methamphetamine.
c. Varying sample pH within the range of 4 and 9 has no significant effect on the assay results.
d. Varying sample specific gravity within the range of 1.003 and 1.040 has no significant effect on the assay results.
