SEMEN & BLOOD DETECTIONS
DETERMINE WHETHER A STAIN IS SEMEN/BLOOD
Use | Peace-of-Mind |
Processing Time | approx. 2 weeks (tests using unusual samples will take longer) |
Accuracy | Varied based on type of sample provided |
Details | Depending on which test you select, these tests determine if a stain is semen/contains seminal fluids or if a stain contains blood. The test will not provide a DNA profile of whose semen it is, but can be used in conjunction with DNA Profiling. At PTC Laboratories, we use visual inspection as well as chemical analysis on the alleged stain(s). These are confirmatory tests that confirm the sample is semen/blood. To generate a DNA Profile from this result, please see our DNA Profiling section. Before purchasing this test, it is important to contact us first, to discuss your requirements and whether this is the right test for you. |
Price | THB 12,300 (if providing a sample other than a cotton tip, an additional THB 8,300 Unusual Sample Fee applies per sample) |
