Should you have a blood test before weight treatment?

When starting medical weight management, your doctor will usually recommend a baseline blood test. The cost is normally Medicare-rebated, and the results shape both safety screening and ongoing monitoring.

What's typically included

A common starting panel: HbA1c (3-month blood-sugar average), fasting glucose, lipid panel (cholesterol breakdown), liver function tests (ALT, AST, GGT), kidney function (eGFR, creatinine), full blood count, thyroid function (TSH), and vitamin D / iron studies if symptoms suggest deficiency.

What your doctor is looking for

Three things. First, safety — anything that would change which treatments are appropriate. Second, baseline — so we can measure the effect of treatment over the next 6–12 months. Third, opportunistic screening — many people in this stage of life are due for these checks anyway, and weight programmes are a good time to do them.

What happens if something's flagged

Often nothing dramatic. Slightly elevated liver enzymes are common in fatty-liver patterns and usually improve with weight loss. Borderline HbA1c (pre-diabetic range) is exactly the kind of finding that justifies treatment. Your doctor will explain anything unusual and decide whether further investigation is needed before treatment starts.

Cost and logistics

Pathology referrals are written by your Fusenite doctor and processed at any Australian Medicare-affiliated collection centre (Sonic Healthcare, Australian Clinical Labs, Healius). Most of the standard panel is bulk-billed; out-of-pocket costs are usually under $50.
