Seeing a disconnect between impersonal big-box labs and the intimate doctor/patient relationship, Dr. Gillespie founded PathAdvantage to fill that gap, addressing those areas that matter most to patients and their providers: accurate, detailed results and fast turnaround.

18 years later, PathAdvantage has become a trusted partner to hundreds of practices dedicated to providing their patients with a better experience. Unmatched pathology expertise, direct access to pathologists for personal and in-depth consultation and 24-hour turnaround on results are just a few of the reasons top providers depend on PathAdvantage.

All Day Pathologist Access

No voicemail, no automated prompts. When you have questions, you need a qualified expert to answer them. Our pathologists are always available when you call.


We care about patients, not money. We proudly invest all resources back into patient care and make decisions based on the patient, not on shareholders or VCs.


With a dedicated team of couriers for specimen transport at multiple daily pick up times for every major hospital in the area, your patients will get results in hours, not days.

Advanced Test Panels
are Standard

Candida speciation, bacterial vaginitis and STI panel testing directly from the ThinPrep vial, Non-invasive DNA Damage Test, the list goes on. Our special menu fits your practice’s needs.

Less Invasive
Biopsy Devices

We stay at the forefront of gynecologic pathology, offering innovative and exclusive biopsy devices. We developed (and are the exclusive provider of) the MatrixBrush, an endometrial sampler that offers a more reliable diagnosis and reduced pain.


Our knowledge, experience and technology provide your patients with more accurate and better care. When it comes to patient biopsy diagnoses, you need knowledge and experience you can depend on.
