Tissue tells the story your imagingcouldn't finish.
Histos is a private histopathology practice in Sydney. We examine glass slides under oil immersion so that your GP, specialist, or you receive a clear, precise answer — not another question.

Referring Clinicians & Patients
What clinicians say
after the report lands.
active referring clinicians
"I've been referring skin biopsies to Histos for four years. The turnaround is genuinely 24 hours, and the reports are written for clinicians — not for other pathologists. My patients appreciate the plain-language summaries."
Dr. Margaret Okafor
GP Principal
Glebe Road Family Medicine, Sydney
"When I have a complex colonic biopsy — suspected Crohn's versus infectious — I want a pathologist I can call. Histos picks up the phone. The IHC turnaround is faster than any lab I've used at the public hospitals."
Dr. James Nguyen
Gastroenterologist
Digestive Health Associates, Parramatta
"After my melanoma diagnosis I wanted a second opinion before committing to wide local excision. The slide review was thorough, the consultation was unhurried, and the pathologist explained every margin measurement. That clarity mattered enormously."
Priya Krishnamurthy
Patient — Second Opinion
Self-referred, North Shore
"The NATA accreditation and RCPA QAP participation gives me confidence when I'm referring high-stakes specimens. I know the methodology is audited. Histos has never missed a deadline on an urgent case."
Dr. Siobhan Brennan
Gynaecological Oncologist
Royal Hospital for Women, Randwick
