Legal Twin Test
The Legal Twin Test is for individuals who need to receive legally admissible documents for use in court. Our legal twin test results reports are legal documents which are admissible in courts throughout North America. Legal twin testing requires a chain-of-custody procedure to be followed during sample collection by an unbiased third party collector/collection site. If you choose the legal test, you cannot collect the samples yourself. You will need to attend an appointment for chain-of-custody sample collection. This ensures proper witnessing, verification of identification and fingerprinting of the individuals involved in the test. Results will be available 3 to 5 business days from the date the samples are received at the laboratory.
