Technical Officer at NSW Health Pathology’s John Hunter Immunology Laboratory Deb Capper is hanging up her well-worn lab coat and retiring after more than 50 years of dedicated service.
Deb’s colleagues gathered this week to farewell their long-standing friend and celebrate an incredible career that spans five decades.
Deb reflected on the highs and lows, and all the changes she’s witnessed in pathology and healthcare.
“I always wanted to work in a lab – after completing my science degree at the University of Newcastle, I knew I wanted to do lab work, especially after completing my work experience over the summer break,” she said.
“I started my first pathology job back in 1974 during my university summer holidays and received a full-time role as a hospital scientist at Newcastle’s Mater Hospital in the biochemistry department in 1976.
“I stayed at the Mater Hospital laboratory from 1976 – 1983 and worked across the blood bank/haematology and biochemistry departments. It was a really varied role, where I got to rotate around all labs, doing all parts of the testing from collecting a patient samples, preparing the samples and then running the tests,” she said.
That hard work paid off, and Deb was given the opportunity to look after the lab as the Acting Head of Biochemistry, when her supervisor took leave to complete her PhD.
“I then changed course and worked as a Research Assistant at the Royal Newcastle Hospital in the Immunology Department in 1999 ‑2000. We were responsible for the saliva testing on the Australian Olympic swimming team for the 2000 Sydney Olympic Games,” she said.
“The saliva testing supported our swimmers to get ready to compete at the Olympics, our testing was able to pinpoint when they got infections and support their health so they could perform at their best.”

Deb said she’s had many different roles and got to work across some of the Hunter’s largest laboratories, making many friends along the way.
“In my current role, I prepare and analyse urine and blood samples that come into the lab testing to determine if patients have myeloma/cancer. I also help support the flow of work in the lab by collecting samples from other departments and helping other colleagues as needed.
“It has been rewarding to have worked for NSW Health Pathology for over 50 years. I’ve seen so many changes across the many roles I’ve worked in at Newcastle’s Mater Hospital (now Calvary Mater Newcastle,) the former Royal Newcastle Hospital and now John Hunter Hospital.
“The work has always evolved, and I have been fortunate to work with so many wonderful colleagues and create lifelong friendships.
“It’s been rewarding to know that I have been a part of an organisation that has grown and adapted to change, while always putting patients first.”
The biggest change Deb has seen has been the automation of machines – shifting from hands on, manual testing approaches to improved technology that automates more of the process.
“In the early days of my career, we used to manually collect blood on the wards and do all testing – now this is handled by specialised teams. The size of labs has also increased significantly – going from small teams where you knew everyone, to now where there’s hundreds of people and many pathology department departments in the John Hunter – it’s a huge operation!
“Despite all these years, I’ve loved donning the lab coat and playing a small but vital role in the important work that NSW Health Pathology does for the people of NSW.”
NSW Health Pathology’s John Hunter Immunology Laboratory Uniter Supervisor Karla Lemmert said Deb’s generous nature will be missed.
“I have personally known Deb for as long as I’ve worked here in pathology. She has worked across multiple departments and in later years worked concurrently in biochemistry and immunology where she ends her career in 2025,” Karla said.
“In that time, she has raised three beautiful children whilst managing a variety of roles in immunology and juggling working shifts in biochemistry and immunology. She was a significant contributor to our department’s research projects over the years, and we’re really going to miss her.”
Deb is swapping the hospital laboratory for the open road.
“I am looking forward to switching off the alarm clock, enjoying a slower pace and the simpler pleasures in life. Hopefully there will be more time for long walks with my husband and doing jigsaw puzzles – one of my favourite hobbies since COVID-19!” Deb said.
“I also look forward to spending more time with my husband, three grandchildren and planning some special holidays in Australia and overseas with family and friends.”
Happy retirement Deb – you will be missed!
