Frequently Asked Questions

Where can I get a DNA paternity test in San Leandro, California?

TestMark DNA has a certified collection site at 13847 E 14th St Ste 100, San Leandro, California 94578. No appointment is needed and results are typically returned in 3 to 5 business days.

Do I need a doctor's order or court order for DNA testing in California?

A doctor's order is generally not required. However, if you are a New York State resident, a prescription, court order, or ordering by other authorized persons is required by state law for all DNA identity or relationship tests.

Can DNA testing be done without the mother present?

Yes. A DNA paternity test can be performed without a sample from the child's biological mother. Including the mother's sample is preferred when possible as it improves accuracy.

How long do DNA test results take near San Leandro?

Results for a standard DNA paternity test are typically returned within 3 to 5 business days from when all samples are received at the laboratory.

Is DNA testing confidential?

Yes. All samples are packaged in tamper-proof bags and processed at an accredited laboratory with restricted access. Results are shared only with authorized individuals and are never released over the phone.

What type of sample is collected for a DNA test?

The standard sample is a buccal swab - a cotton swab rubbed gently inside the inner cheek. It is painless, non-invasive, and provides the same accuracy as a blood sample.

Will DNA test results be accepted in court?

Results from a legal DNA paternity test performed at an accredited facility may be accepted in court, provided the chain-of-custody form was completed according to laboratory guidelines. Non-legal test results are not intended for court use.

Is DNA paternity testing covered by health insurance?

DNA paternity testing is considered a non-medical test and is not covered by health insurance plans.
