WHAT OUR CUSTOMERS SAY ABOUT US

Having researched many private DNA testing companies, I found PTC Laboratories is the most reliable one. I rapidly got professional information from my first call with PTC staff. I also got the case number and tracking information of my DNA sample when it was on the way to the lab in USA. I received my result as soon as testing was completed, which was much quicker than I expected!

GLORIA (THAILAND),
INVASIVE PRENATAL PATERNITY TEST CLIENT

I was always told I was born to a Thai woman and her American husband. An ancestral DNA test showed that I was 100% Asian. I then reached out to a friend of mine… A few weeks later, the lady from city hall emailed that she discovered I was adopted, and she had tracked down my birth mother. We decided a maternal DNA test was in order. PTC Laboratories made this test easy and effortless. I was so shocked and amazed when the maternal DNA test came back positive – she is my birth mother! A huge thank you to PTC Laboratories for making this possible!

WIL SALMONSON (USA/THAILAND),
MATERNITY TEST CLIENT

It is a pleasure to testify that the team of PTC Laboratories in Thailand are: very professional, very efficient, very accurate in every step of the test, completely independent (the laboratory is located in the USA) and always available. The team is as well able to manage in a few hours the organization of an international test (alleged father in Europe, mother in Thailand for example). At the end, I highly recommend PCT Laboratories in case of prenatal paternity test

GREG (FRANCE),
NON-INVASIVE PRENATAL PATERNITY TEST CLIENT

I was really impressed by the service and guidance throughout the whole process. We never done such a test before. We have been quiet nervous and insecure. The help and support given by PTC was outstanding. I am happy that we decided to go for the paternity test, as we now have the clearance for ourself. Special thank’s to Khun Kheng. You made it as smooth as possible

CARMEN (PHUKET),
LEGAL PATERNITY TEST CLIENT

Thank you PTC-Laboratories for your wonderful service. We were in contact with several different AABB Accredited DNA testing facilities but in the end the choice was obvious. PTC-Laboratories was able to met our demands on all occasions and their service was prompt, professional and forthright. We would especially like to thank Quah Boon Kheng from the Thailand office for his personable character and willingness to go the extra mile. We required a Legal Paternity Test for Swedish Citizenship, and Kheng was able to meet us the day after we notified him of the arrival of our son. The samples were collected at the hospital without a fuss, and couriered directly to the USA for analysis. We also requested the Express Next-day service and our samples were analyzed the day of arrival in the USA, and the results were couriered to Sweden on the next working day! We can highly recommend PTC-Laboratories, and especially their office in Bangkok Thailand! Thank you again PTC Laboratories.

GRAWE FAMILY (SWEDEN),

Going with PTC and making a DNA paternity test with them was fast, reliable, secure and painless. Within an hour, their manager took care of me and arrange via emails and phone calls a time for the same day to collect our genetic samples. Two days after, samples arrived at their lab in the states. After 6 days including a long weekend, I had my results by email. The documents arrived shortly after. The results of this test can also be used in courts. Don’t look further, great deal and excellent value for the money

DAVID SIRINNONT (USA),

My partner and I were very lucky to have met the representative of PTC Laboratories in the hospital. We were in need of an express paternity test, and the company’s representative was in the right place at the right time. We received clear and detailed information regarding the process, and felt we are in good hands. The process in Thailand was simple and friendly and the results were given to us in a very short while, shorter than the other local options estimations. Being in the middle of a bureaucratic process, we were glad to receive this service from PTC Laboratories, it was professional, trust worthy and friendly, THANK YOU!

AMI R. (ISRAEL),
EXPRESS LEGAL PATERNITY TEST CLIENT

I am Thai Adoptee and I have been searching for my birth family in Thailand. With help of PTC Laboratories I have been able to do DNA Test without me being there in person. They have been very understanding about my case. They were able to send me a test in the USA and go personally to the home of the people that I wanted tested. They were very professional and quick to respond to any questions I had. My results came back quick and the test was very affordable for me. I will definitely use them in the future. Thank you PTC Laboratories.

LISA KININGER (NEW YORK, USA),
MATERNITY TEST CLIENT

After some research I decided PTC Laboratories Thailand looked to be the most credible (and accredited) paternity testing service available that was required for my son’s citizenship application. I was not disappointed and was in fact pleasantly surprised by the level of follow-up and personalized attention. After requesting the service online I was immediately contacted and the various options were explained clearly and patiently. I was also informed that there was a doctor nearby who had kits and could gather the samples. A representative then called to make sure I had received the email results and re-checked the address the paper lab results would be sent to. PTC staff clearly treat this potentially life-changing test with discretion, sincerity and professionalism, giving it the importance it deserves. I would recommend PTC to anyone looking for a paternity testing service.

NEIL MAEDEL (CANADA),
EXPRESS LEGAL PATERNITY TEST CLIENT

I was recommended the services of PTC Laboratories for a paternity test. The representative was a pleasant young man who presented as polite and efficient. The results were punctual and communication was good throughout. I would certainly have no hesitation in recommending the services of PTC Laboratories. Value for money, good efficient service.

LABORATORY CAPABILITIES

QUESTIONS YOU SHOULD ASK YOUR DNA LAB

Yes. We are one of the very few foreign laboratories that can provide authenticated results that are legally accepted in Thailand, and also abroad. Our results are available in English and Thai. Our laboratory is located in Missouri, USA, with a customer office in Bangkok, Thailand.

Absolutely. PTC Laboratories has more than 2,000 certified collection centers around the world. In Thailand, our customer care office is in Bangkok, but we also have certified collection centers around the country, including in Pattaya, Phuket, Chiang Mai, Koh Samui, Khon Kaen, Krabi, and Hat Yai to name a few. If we don’t have a collection center near you, we will work closely with you to find a clinic and will explain the process directly to the doctor. We also arrange for your samples to be sent to us via first-class courier.

Yes. Our laboratory accreditations are unmatched in Thailand (AABB, ISO17025, ASCLB/LAB, NYSDH, CLIA, CAP); this means that DNA tests conducted by laboratories located within Thailand will not be accepted by Immigration Departments of other countries, such as the USA and UK. PTC DNA results are accepted in Thailand, USA, UK, Switzerland, Germany, France, Japan, New Zealand, Singapore, Malaysia, Taiwan, Sweden, and many more countries.

Yes. We use both specific ethnic and geographical DNA databases in our analysis, meaning Thai people are compared against a Thai database. North American people are compared against a North American database. And so on.

Yes. We offer a higher guarantee of 99.99% inclusion (compared to just 99% offered by local labs and some other AABB-accredited labs) and 100% exclusion rates. We consider anything less than these standards to be ‘inconclusive’, and you will be refunded. Our guarantee stands even in the event of finding DNA mutations in your sample, as well as in motherless tests and at-home/peace-of-mind tests.

We begin with testing 16 loci, however, our prices include continued testing until our guarantee of 99.99% inclusion or 100% exclusion is met; this means if we find a mutation in the DNA, or need to re-test with more than the initial 16 loci, or need to move to RFLP testing, you will not be charged extra.

OUR 99.99% GUARANTEE AND WHY IT’S SO IMPORTANT

There’s a big difference in small numbers, and this is why it’s important to find a lab that offers 99.99% probability of paternity. The different between a 99% and 99.99% probability, is that a result at 99.99% is 100 times more accurate.

PTC Laboratories guarantees a minimum probability of paternity of 99.99% on every DNA normal paternity test (motherless tests, at-home tests and mutations are all included in our guarantee). At a 99.99% probability of paternity, on average, the identified DNA genetic pattern will fit no more than 1 in every 10,000 men in the population group. And most of our DNA paternity tests are even more discriminating than that, at 99.999+%.

Often, labs that issue positive results of 99% probability of paternity will then offer to continue testing using a different method, such as RFLP, at an additional charge. At PTC Laboratories, our test fee includes testing, by whatever method necessary, to reach a 99.99% probability of paternity for all positive tests, including switching from PCR to RFLP testing, with no extra or hidden charge to you.
