DNA Fingerprinting

Paternity Test

How To Prepare

Tell your doctor if you have had a blood transfusion within the past 3 months. No other special preparation is required before having DNA fingerprinting.

Talk to your doctor about any concerns you have about the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form (What is a PDF document?).
