What biological samples will be taken for DNA testing?

Blood or buccal samples will be taken. Only blood samples will be archived for five years.

Can samples be collected outside the DNA Analysis Laboratory NSRI-UPD?

Yes. The DNA Analysis Laboratory NSRI-UPD L has a Sampling Kit that can be sent to a specified licensed medical person who may collect samples and mail the accomplished kit back to the laboratory via courier. Alternatively, arrangements can be made for a team from the DNA Analysis Laboratory NSRI-UPD to collect samples at other locations.

When will the results of DNA testing be ready?

Results of routine DNA tests are ready within 14 working days from the date of sampling and completion of all requirements. More complex cases will require more time.

Can the results of the analysis be used in court?

Yes. DNA testing has been ordered and results admitted as evidence in cases of child support, inheritance disputes and settlement of estate, insurance and for immigration purposes. The Philippines Supreme Court promulgated the “Rule on DNA Evidence” in October 2007.  The full text of the Rule may be downloaded from the Supreme Court website: http://sc.judiciary.gov.ph/resolutions/2007/oct/A.M.06-11-5-SC.pdf
