About Us

We take pride in our ability to offer you high-impact diagnostic results by providing you with a PoC laboratory from next-generation technologies. 

Our Doc In A Box program also provides strategic, tactical, and operational white coat lab management to maximize patient care without requiring time from your employees.

You get the benefit of having PoC diagnostics without you even knowing we are there.


Welcome to USA Doc Lab

USA Doc Lab provides dedicated hands-off solutions to bring a point of care lab to private doctors. From the initial facility audit to full lab management, we do it all so the doctors can focus their attention on their patients. PoC diagnostics will become the standard as we move into the future of healthcare. We give the practice faster results with antibiotic resistance reports, which leads to proper treatment courses.

This leads to patients getting issues resolved faster and preventing them from taking antibiotics that were not needed. For insurance companies, this dramatically reduces paying for revisits and paying for prescriptions twice while reducing paying for mistakes created from insufficient testing. We create a new revenue stream for the doctors, save patients time and money by only needing one appointment to resolve issues.

Joshelle Tsinnijinnie
Lab Tech for Arizona State Urology

Joshelle is a member of the Navajo Nation tribe, who graduated from Northern Arizona University with a bachelor’s degree in biomedical of sciences. Her passion for performing PCR testing began when she worked in a molecular biology lab during her undergraduate years. Her research consisted on identifying oncomir microRNA-27a polymorphisms associated with prostate cancer in Native Americans, as well as evaluating genotype frequencies within the chitinase gene. It was with that experience that she learned the importance of genetic testing and she knew that her pursuit in helping patients would be through medical testing. Which led her to work as a molecular laboratory technician at Sonora Quest Laboratories aliquoting covid samples. Several months later, she now enjoys working and applying her skills with our company processing urinary samples at Arizona State Urology.

Gabriel Rivera Del Toro
Lab tech for Urology Associates of Silicon Valley
My name is Gabriel Rivera Del Toro; I am originally from Puerto Rico. I completed my Bachelor’s Degree in Microbiology at the University of South Florida. At USF, I dedicated my years as a student orientation leader to helping both new students and families embrace their journey as
they start a new chapter of their lives. After graduating, I moved to San Diego to work for Labcorp as a Clinical Lab Technician, where I worked heavily in the detection of Covid-19 in patient samples and DNA sequencing of patients samples to study the possibility of different variants. In this job I hope to gain a better theoretical knowledge and more practice in other molecular biology techniques such as PCR, RT-qPCR. I am super excited to be part of a team
that wants to bring diagnostics back into the physician’s office to facilitate and accelerate treatment. In the future, I hope to take my skills and knowledge into a Research Associate position in a company that values teamwork, leadership, integrity, and growth.

Our mission is to decentralize high complexity reference laboratories
