Please see the Product Insert (included in each box of test strips)

Materials Needed

• Bio Detect Test Strip
• Bio Detect Sample Buffer
• Disposable Bulb Droppers (included with each test)
• Disposable Sample Vials
• Disposable Polyester-tipped Swabs
• pH test paper

Sample Preparation and Evaluation

The key to sampling is to sample moderately. The test strips are
very sensitive and require about a microgram of material, dispersed in
one milliliter (ml) of buffer solution to obtain a valid result.
A pH test is also recommended to guard against the inadvertent
evaluation of harsh chemical agents, which can damage the test strip.

Swipe Samples

1) Fill the sample vial with 1 ml of Sample Buffer.
2) Collect the sample by swiping the contaminated surface with
a polyester-tipped swab.
3) Transfer the sample by placing the swab in the vial, then stir
to disperse.
4) Cap the vial and agitate vigorously for 10 seconds.
