Every vial, swab, and signature follows chain-of-custody protocols built for courtrooms and immigration officers — not for the mail-order DNA kit economy.
Results admissible in family court, immigration proceedings, and federal cases.
Every specimen processed in facilities meeting the highest federal standards.
Court deadlines, immigration filings, employment decisions — engineered for urgency.
Your information is never sold, never shared. Confidentiality is the baseline, not the upgrade.
Paternity, immigration, siblingship, grandparentage, Y-STR, and twin zygosity. Court-admissible chain of custody or peace-of-mind, your choice.
Mobile collection under valid provider orders. Physician-backed ordering portal available for individuals without a doctor.
Most clients find the right test in under two minutes.
A direct comparison between the alleged parent and the child.

Select DNA testing or phlebotomy. Not sure which DNA test you need? Use our test finder or call us — we'll walk you through it in five minutes.
Upload your physician's lab order, or order through our physician-backed partner portal if you don't have one. Court orders and attorney requests handled directly.
Katy-based mobile collection at your home or workplace, by appointment. A trained professional handles the entire chain of custody under HIPAA-compliant protocols.
Most results in 24–72 hours, sent securely to your provider, attorney, or directly to your client portal. Urgent requests are prioritized.
We needed court-admissible paternity results before a custody hearing twelve days out. BioXpress had the chain of custody documented, the collection scheduled within forty-eight hours, and the results in our hands ahead of the deadline. That kind of reliability is rare.
Having the blood draw done at my home instead of taking half a day off work was worth every dollar of the mobile fee. The collector was professional, fast, and the lab had my results in two days.
The USCIS process is unforgiving on documentation. BioXpress walked us through every form, handled the chain of custody perfectly, and our petition cleared without a single follow-up request.

We're AABB-accredited, our chain of custody is court-defensible, and every specimen is collected by a trained professional. The result holds up where it matters.
Most results arrive in 24 to 72 hours. We understand that court deadlines, immigration filings, and employment decisions don't wait, so urgent requests can be prioritized when needed.
All data and results are handled in full compliance with HIPAA and AABB standards. Your information is never sold, never shared, and never discussed outside the people directly involved in your test.
For non-legal DNA testing, we offer mail-in kits nationwide. For legal/court-admissible work, our collection service is Katy-based and mobile-only. Call us to confirm availability for your location or discuss coordination with an accredited collector in your area.
