Frequently Asked Questions

Yes. Testing can be performed to indicate the presence of blood, saliva, or semen in a sample. The test relies on the use of chemicals, which change color when coming in contact with blood, saliva, or semen.



Yes. A profile can be obtained from urine. Over time bacteria in urine can degrade DNA, so fresh or frozen urine is the best type of sample to test.

Yes. Instead of using nuclear DNA testing, we would use mitochondrial DNA testing. The mitochondrial genome is highly polymorphic or varies greatly from one person to another, making it useful for human identification. Because mitochondrial genes exist in high amounts within a cell they are very useful when analyzing samples that lack nuclear DNA. Mitochondria DNA testing is bit more expensive than Nuclear DNA testing involved with your case.

Yes. Y-STR testing can be used to obtain a male profile in these instances. However, a minimum amount of male DNA must be present. If a sample’s minor component is male with the major component being female, then Y-STR testing may reveal a male DNA profile. Additionally, If there are multiple male contributors in a sample, Y-STR testing may help to differentiate the individual contributors.

This depends on the type and the condition of the sample. We specialize in extracting DNA from unusual and difficult forensic samples. Contact us to discuss the details

For reference samples, we prefer buccal swabs or blood cards, but we will also accept whole blood. If you are sending whole blood, please use appropriate shipping materials to prevent breakage.
