With the PSA test (preliminary investigation of the disputed traces), we disprove or confirm the suspicion, that the object contains traces of sperm. Most often, we are looking and investigating visible (also invisible) traces on the underwear, pants and other outerwear, paper or cotton wipes, car seats and many other surfaces.
By prior arrangement you can bring the sample in the company’s headquarters, where we will perform immunochemical testing in the shortest time possible, and let you know about the results.
How to handle a trace or a sample, which you want to get tested?
Deliver the sample in the shortest time possible,
When handling a questionable object or trace, use protective gloves,
Do not smell or taste the sample,
Do not expose the sample to a thermal treatment; if it is wet, it should dry naturally (do not dry it with a hair dryer, in a tumble dryer or in the oven, and don’t iron it),
Store the sample in an paper envelope, and in the case of personal delivery don’t close the envelope completely,
Do not store the sample in a plastic bag or plastic container,
If the sample will not be sent immediately, exceptionally freeze it, but household freezers are not recommended for long-term storage (more than 3 months).
