TEST DETAILS

Description

This test determines if a stain is, or contains, blood. The test will not provide a DNA profile of whose blood it is (see here for DNA Profiling). At PTC Laboratories, we use visual inspection as well as chemical analysis on the alleged blood stain(s). These are confirmatory tests that confirm the sample is, or contains, blood.

This service is also available to law enforcement agencies who need reliable and conclusive testing of rape kits or other forensic evidence. 

Samples submitted to PTC Laboratories could be a bed sheet, tissue paper, plaster, an article of clothing, or other forensic evidence. The stain should be at least 5 x 5 mm in size. However, these types of samples are known as Unusual Samples and will incur an unusual sample fee, as we must first extract the DNA in order to analyze it. You can view our Unusual Samples page to see what other types of samples can be used for this testContact us for more information.

On the other hand, if the stain is fresh, use sterile cotton tips to swab the stain. We also have DNA Sample Collection Kits for this use and can post a kit to you. Cotton swabs are considered standard samples and we do not charge an unusual fee if you submit this type of sample, however you must be very careful and precise in how you transfer the suspected semen onto the cotton swab.

Please contact us to have a confidential discussion about the suspected stain and the type of sample you wish to submit. 

ONCE I KNOW IF THE STAIN CONTAINS BLOOD, I ALSO WANT TO KNOW WHO IT BELONGS TO. HOW DO I KNOW THIS? 

Once you know whether the provided sample contains blood, you can decide to do a DNA Profile of the blood. This will generate a genetic profile of the donor of the blood. You then need someone to compare the blood's DNA profile to, and see if they match. To do this, you also need to do a DNA profile of the person/s you want to test the blood profile against.

For example, in criminal cases, a suspect will give a DNA sample, which will be used to create a DNA profile. This genetic profile is then compared against the DNA profile generated from the blood sample. Similarly in infidelity cases, a DNA sample from a spouse or partner will be used to generate a DNA Profile, and this would be compared against the DNA profile generated from the blood sample.

In the case of infidelity cases, it is advised to also send a DNA sample of your spouse or partner at the same time that you send the initial stain containing suspected blood. This will save you having to pay a second courier fee. Please see DNA Profiling for more information.

Please note that there is no chain-of-custody of the initial blood sample, this test (and therefore any DNA Profile comparisons) can only be used for peace-of-mind purposes. 

Before purchasing this test, it is important to contact us first, to discuss your requirements and whether this is the right test for you.

Important Information


WHAT CAN THIS TEST BE USED FOR?

  • As there can be no chain-of-custody of the initial blood sample (you collect your own samples), a Blood Detection Test (and therefore any related DNA Profile comparisons based off of the initial blood sample) can only be used for peace-of-mind purposes. 
     

HOW LONG WILL IT TAKE TO GET MY RESULTS? 

  • Testing times can vary depending on the samples provided. Generally, for tests with good cotton swab samples it will take approx. 2 weeks. Tests using unusual samples will take longer. This includes both the time it takes to send your samples to our lab in the USA (2 business days) by first-class, international priority courier, and also the testing time at our lab.
     
  • If you are in a hurry, we have an express testing option. Note that if you are using unusual samples in this test, we may not be able to conclude the test within the express timeframe; in this case, you will be refunded for the express fee. Scroll down the page to add this option to your order.
     
  • Your results will be sent to you immediately by email. Your physical results will be sent to your via regular post and will arrive in Thailand approximately 2 weeks after you receive your emailed results. 
     
  • If you’re in a hurry, you can also opt to have your results sent via first-class, international priority courier for an additional fee, and your results will arrive within approximately 2 business days. Scroll down the page to add this option to your order.
     

WHAT IS THE GUARANTEED PROBABILITY OF THIS TEST?

Provided that the samples are good, you can be assured of 100% accuracy in determining whether the sample is, or contains, blood.

WHAT KIND OF DNA SAMPLES CAN I USE?

  • If the stain is fresh, use sterile cotton tips to swab the stain. We also have DNA Sample Collection Kits for this use and can post a kit to you. Cotton swabs are considered standard samples and we do not charge an unusual fee if you submit this type of sample, however you must be very careful and precise in how you transfer the suspected semen onto the cotton swab. Please contact us to have a confidential discussion about the suspected stain and the type of sample you wish to submit. 
     
  • If normal samples are not possible to obtain, you can view our Unusual Samples page to see what other types of samples can be used for this test. Samples submitted to PTC Laboratories could be a bed sheet, tissue paper, plaster, an article of clothing, or other forensic evidence. The stain should be at least 5 x 5 mm in size. Most unusual samples will incur a fee, as we must first extract the DNA in order to analyze it. Contact us for more information.
