PERFORMANCE CHARACTERISTICS<br />
Accuracy<br />
A side-by-side comparison was conducted using the AMP One Step<br />
Amphetamine <strong>Test</strong> Device (Urine) and a lea<strong>di</strong>ng commercially available<br />
AMP rapid test. <strong>Test</strong>ing was <strong>per</strong>formed on 300 clinical specimens. Ten<br />
<strong>per</strong>cent of the specimens employed were e<strong>it</strong>her at -25% or +25% level of the<br />
cut-off concentration of 1,000 ng/mL Amphetamine. Presumptive pos<strong>it</strong>ive<br />
results were confirmed by GC/MS. The following results were tabulated:<br />

A study was conducted at 3 physicians’ offices by untrained o<strong>per</strong>ators using 3<br />
<strong>di</strong>fferent lots of product to demonstrate the w<strong>it</strong>hin run, between run and between<br />
o<strong>per</strong>ator precision. An identical panel of coded specimens containing, accor<strong>di</strong>ng<br />
to GC/MS, no Amphetamine, 25% Amphetamine above and below the cut-off,<br />
and 50% Amphetamine above and below the 1,000 ng/mL cut-off was provided to<br />

Effect of <strong>Urina</strong>ry Specific Grav<strong>it</strong>y<br />
Fifteen (15) urine specimens w<strong>it</strong>h specific grav<strong>it</strong>y ranging from 1.001 to<br />
1.032 were spiked w<strong>it</strong>h 500 ng/mL and 1,500 ng/mL of Amphetamine<br />
respectively. The AMP One Step Amphetamine <strong>Test</strong> Device (Urine) was<br />
tested in duplicate using the fifteen neat and spiked urine specimens. The<br />
results demonstrate that varying ranges of urinary specific grav<strong>it</strong>y do not<br />
affect the test results.<br />
Effect of <strong>Urina</strong>ry pH<br />
The pH of an aliquoted negative urine pool was adjusted to a pH range of 5<br />
to 9 in 1 pH un<strong>it</strong> increments and spiked w<strong>it</strong>h Amphetamine to 500 ng/mL<br />
and 1,500 ng/mL. The spiked, pH-adjusted urine was tested w<strong>it</strong>h the AMP<br />
One Step Amphetamine <strong>Test</strong> Device (Urine) in duplicate. The results<br />
demonstrate that varying ranges of pH do not interfere w<strong>it</strong>h the <strong>per</strong>formance<br />
of the test.<br />
Cross-Reactiv<strong>it</strong>y<br />
A study was conducted to determine the cross-reactiv<strong>it</strong>y of the test w<strong>it</strong>h<br />
compounds in e<strong>it</strong>her drug-free urine or Amphetamine pos<strong>it</strong>ive urine. The<br />
following compounds show no cross-reactiv<strong>it</strong>y when tested w<strong>it</strong>h the AMP<br />
