bulletWe will send you instructions for mailing your samples to the lab.

bulletYou must include a serial number (that we provide) attached to your article before sending it to the lab.


Important information about these studies

bulletThe results of these studies are not admissible in a court of law due to the absence of the chain of custody.  The chain of custody refers to the various chain of "hands" that the individual sample passes through. A legal chain of custody requires the samples to be collected in the presence of a neutral third party at a lab or hospital facility where all parties are photographed to verify their identity, and specific handling instructions are met.  


bulletThis test is a destructive test, as there will be small holes made in the article where the sperm is extracted.


bulletSample Collection Procedure
bulletIt is very important not to store the sample in a plastic bag.  
bulletAllow the sample to dry naturally.  
bulletIf you will not be sending the sample for a few weeks, please freeze it,  but allow it to thoroughly dry after thawing and before mailing it to the laboratory.  
bullet Always mail the sample in a paper envelope.


bulletIf the stain to be tested is not obvious or contained within a small area, circle the specimen in question with a marker or tape to ensure the lab knows what you want tested.

Types of Tests

Semen/Sperm/Saliva Detection

Semen and Sperm Detection Inc (SSDI)

Order the semen detection study below if you would like to determine if a stain or fluid is semen with or without the presence of sperm.  


These tests are preformed:

Prostate Specific Antigen (PSA) .  Unlike the acid phosphatase presumptive test, detection of the PSA requires the presence of the semen protein without the need of the target to perform an enzymatic function. No longer will semen detections be presumptive (additional PSA information). 


Microscopic inspection - The substance is wet mounted and examined under a high power microscope for the presence of sperm.


Acid Phosphatase (AP) - This is a 97% presumptive test for the enzyme PH level found primarily in semen.  This test will indicate the mass of the semen if positive.


This test normally takes 1-2 business days (Monday through Friday).  Guaranteed same day service is available at an additional charge.

Non-Destructive Semen/Sperm Detection, Article Returned.  This test takes up to 3 business days and is not as powerful as the destructive test.  This test is not recommended unless you must have the article returned without holes that are necessary to conduct the normal semen/sperm test.  The stained area will be blotted and the blotted material will be tested. One sample. $264.00
