What are the requirements for same-day results?

To ensure this turnaround, you must select the Express Same-Day Service at the time of booking. Ensure all participants (the child and the alleged father) provide clear, uncontaminated swabs. We strongly advise using guaranteed special delivery or a direct courier if sending samples from home.
