Pro-Lab Diagnostics has proudly called Texas home since 1986 and effectively changed the U.S. Health and Safety market with the introduction of the original specimen transport bag – the TransVelope™. Since opening, Pro-Lab has successfully expanded its product offering to include a variety of general microbiology products, lab equipment and molecular diagnostics.

NQA and ANAB accreditation

In 2020, when the pandemic swept the globe, Pro-Lab Diagnostics’ CEO, Robert Rae, saw the need to assist the community by offering quick and accurate COVID-19 testing and results. Chosen as one of the top companies to receive an approved FDA EUA for COVID-19 Testing, Labtest Bio’s COVID-19 drive-thru was open to the public in Round Rock, TX.

Since the opening of the laboratory, Labtest Bio has expanded to perform COVID-19 collection and testing for the general public, major sports teams, accredited universities and film/tv productions.

The 24 hour turnaround time has been the #1 priority for the Labtest Bio’s’ team. That has only been achieved through utilizing their novel molecular diagnostic proprietary ProAmpHT Isothermal Amplification – an innovative, rapid, and cost-effective alternative to PCR.

With the sky being the limit, Labtest Bio now offers an extensive line of diagnostic panels to improve quality patient outcomes through innovative diagnostic methods.

To learn more about these panels and how we can improve the quality of your patient’s outcomes, contact us today!
