Do I have to fast for a hormone panel?

If it includes fasting glucose, insulin or lipids — and most comprehensive panels do — then yes, 8–12 hours with water only. Hormones themselves are timed rather than fasted: the aim is a morning draw, ideally between 7am and 10am.

Do I need a referral for a private blood test in Hamilton?

Not for the panels FORM sells. You order online and attend a collection centre with the request form we issue. A referral from a GP is only required if you want the test publicly funded.

What time of day should I book?

As early as the collection centre allows. Testosterone and cortisol both follow a daily rhythm and are highest in the first hours after waking; the reference ranges assume a 7am–10am sample. An afternoon draw can read 20–30% lower for no other reason than timing.

Can one low result tell me something is wrong?

No. A single out-of-range value is a prompt to confirm, not a conclusion. Acute illness, a hard training session, poor sleep, a recent fast or a mistimed draw can all move a marker. Anything clinically important should be repeated on a second morning sample before it is acted on.

About our medical lead.

FORM is a pathology testing service for men in Hamilton who want a complete read on their hormones, thyroid, metabolic health and nutrient status — not the two or three markers a standard check-up runs. Accredited laboratory, collection centres across the CBD, Chartwell, Te Rapa, Rototuna, and a written report that explains what every number means.

What you can test in Hamilton. The full panel covers total and free testosterone (calculated from SHBG and albumin), sensitive estradiol, LH, FSH, prolactin, DHEA-S and morning cortisol; TSH with free T4 and free T3; fasting glucose, insulin and HbA1c; a full lipid profile including ApoB; liver, kidney and full blood count; ferritin and iron studies, vitamin D, vitamin B12 and folate; and inflammatory markers. The breadth is the point — a low testosterone reading is frequently downstream of poor sleep, iron deficiency, thyroid dysfunction, insulin resistance or chronic inflammation, and none of that is visible on a hormone-only screen.

How collection works. Collection runs through an accredited community pathology network — you book online and attend a collection centre near you. Standard opening hours are weekday mornings, which suits the early fasting draw hormone panels need. Bring photo ID and your request form. Fast for 8–12 hours if your panel includes glucose, insulin or lipids, drink water normally, and aim for a draw between 7am and 10am so the hormone markers are comparable to their reference ranges.

Waikato collection rooms run on tighter weekday hours than Auckland's, and the outlying sites at Cambridge and Te Awamutu can close over lunch. Confirm the hours for your chosen room before you commit to a fasting morning.

What the public system covers, and what it does not. Publicly funded testing through Te Whatu Ora is available when your GP considers it clinically indicated, and is limited to that. Tests you order yourself are not publicly funded, and several markers on a comprehensive panel are not routinely funded even on a GP request. That is the trade-off: you pay for the panel, and in exchange you get the full picture in one draw rather than a partial screen spread across several visits.

Reading the results. Every panel comes back with a written report from Dr. Nikola Topalovic (MD PhD), FORM's medical lead. It walks through each marker, flags what sits outside range, and identifies what is worth raising with your own doctor. He is registered to practise in Indonesia and is not registered with the Medical Council of New Zealand, so the report is expert health information rather than New Zealand medical advice, and it is not a diagnosis. Clinical decisions — including any decision about medicines — belong to your own New Zealand-registered doctor.
