GLP-1 Blood Test in Australia: The Complete Monitoring Guide
Order a private GLP-1 blood test online in Australia, no GP referral required. Track pancreatic, thyroid, liver, kidney and metabolic markers before and during therapy with a GLP-1 receptor agonist medication.
A GLP-1 blood test in Australia is now one of the most commonly requested private pathology panels. As GLP-1 receptor agonist medications have become more widely prescribed for type 2 diabetes and weight management, regular blood monitoring has become essential. Importantly, these medications affect multiple body systems including pancreatic, thyroid, liver, kidney, glucose and lipid metabolism. As a result, comprehensive blood testing before, during and after treatment is recommended by Australian clinical guidelines.
However, standard Medicare-rebated pathology often caps which biomarkers can be ordered. Specifically, many comprehensive monitoring panels require additional referrals or aren't covered. Consequently, a growing number of Australians on GLP-1 therapy are turning to private, self-request pathology to access the markers their prescribing clinician wants tracked.
This guide explains exactly what a GLP-1 blood test covers, when to test, which markers to track, and which panel suits the stage of treatment you're at. For broader context on the wider shift to private pathology, see our overview of why private blood tests are growing in Australia.

This content is for general information only and is not medical advice.
A GLP-1 blood test is a private pathology panel designed for people taking or considering a GLP-1 receptor agonist medication. It tracks the biomarkers most affected by these medications — pancreatic enzymes (lipase, amylase), thyroid function (TSH), liver function (ALT, AST, GGT), kidney function (creatinine, eGFR), glucose, HbA1c, full blood count and lipid profile — to establish a baseline before treatment, monitor response during treatment, and screen for potential side effects.
What Are GLP-1 Medications?
GLP-1 receptor agonists are a class of medications that mimic glucagon-like peptide-1, a natural gut hormone that regulates blood sugar, appetite and gastric emptying. Originally developed for type 2 diabetes, they are now also prescribed in Australia for chronic weight management. Importantly, every medication in this class is a prescription-only Schedule 4 medicine and can only be initiated by a registered medical practitioner.
The GLP-1 class of medications
GLP-1 receptor agonists are typically administered as a once-weekly or daily injection, with oral formulations also available. The class includes medications based on the active ingredients semaglutide, tirzepatide, liraglutide and dulaglutide. Each medication has its own approved indications listed on the Australian Register of Therapeutic Goods (ARTG). Specifically, your prescribing doctor will determine which (if any) is appropriate for your situation based on your clinical history, medical needs and treatment goals.
Important: MediTests does not prescribe, supply or sell any GLP-1 medication. We are a private pathology service. Any questions about which GLP-1 medication is appropriate for you, how to obtain it, the dose, or whether to start or stop it must be discussed with your prescribing medical practitioner.
How GLP-1 medications work
GLP-1 receptor agonists work by mimicking the natural GLP-1 hormone released by your gut after eating. Specifically, they:
- Stimulate insulin release when blood sugar is elevated
- Suppress glucagon (the hormone that raises blood sugar)
- Slow gastric emptying, which can affect how full you feel
- Act on hunger centres in the brain to influence appetite
Notably, these widespread effects across multiple body systems are why GLP-1 monitoring blood tests cover such a broad range of markers. The same mechanisms that produce the clinical effects can also affect organs that benefit from careful monitoring under the direction of your prescribing clinician.
Why GLP-1 Medications Need Regular Blood Monitoring
GLP-1 receptor agonist medications affect systems across your whole body. As a result, regular blood monitoring — ordered by your prescribing clinician or self-requested through a private pathology service — supports informed conversations with your healthcare provider, helps your clinician optimise your dose, and provides objective data on how your body is responding to treatment.
Pancreatic monitoring (lipase and amylase)
GLP-1 medications can cause modest elevations in pancreatic enzymes — lipase and amylase — as a normal pharmacological effect. However, significant elevations may indicate pancreatitis, a serious side effect that requires urgent medical attention. Therefore, baseline and ongoing lipase and amylase testing is essential.
Thyroid monitoring (TSH)
Thyroid function (TSH) baseline testing before and during therapy is standard clinical practice. Your prescribing clinician will discuss any specific personal or family history considerations relevant to your situation, including questions to raise about thyroid history when considering any new medication.
Liver function monitoring
Establishing a baseline of liver function (ALT, AST, GGT, bilirubin) before starting therapy and tracking it during therapy gives both you and your clinician objective data on how your liver is responding over time.
Kidney function monitoring
Because GLP-1 medications are renally cleared and can cause nausea, vomiting and dehydration in early stages, kidney function monitoring (creatinine, eGFR) is recommended to ensure your kidneys are handling the medication well.
Glucose and HbA1c monitoring
For people with type 2 diabetes or insulin resistance, HbA1c is the most reliable indicator of long-term improvement in metabolic control. Specifically, it shows your average blood sugar over the previous 2 to 3 months and is the primary marker prescribers track to assess treatment efficacy.
Nutritional deficiency monitoring
Because GLP-1 medications reduce appetite and slow gastric emptying, some people develop nutritional deficiencies over time — particularly vitamin B12, vitamin D, folate and iron. As a result, comprehensive long-term monitoring should include these markers to catch absorption issues before fatigue, brain fog or other symptoms set in.
When to Get a GLP-1 Blood Test
Australian clinical guidance for GLP-1 monitoring generally recommends bloodwork at three key stages:
Before You Start (Pre-Treatment Baseline)
First, get a baseline panel before your first GLP-1 dose. This establishes your starting point and flags any underlying issues your prescriber needs to know about. Specifically, baseline testing should cover pancreatic enzymes, thyroid function, liver function, kidney function, glucose, HbA1c, lipids and a full blood count. The GLP-1 Readiness Blood Test ($199) is purpose-built for this baseline.
3 Months After Starting (First Check-In)
Next, your prescribing clinician may recommend retesting at the 3-month mark to review how your body is responding and identify any markers that have shifted. Importantly, this is typically when changes in pancreatic enzymes may become apparent, and when HbA1c trends start to emerge. The GLP-1 Progress Blood Test ($249) is designed for this check-in.
Every 6 Months Thereafter
Then, once your dose is stable, your clinician may recommend ongoing testing every 6 months to monitor long-term trends including nutritional, hormonal and cardiovascular markers. For comprehensive long-term review, the GLP-1 Extended Health Review ($469) adds 50+ markers including B12, vitamin D, cortisol, ApoB and homocysteine.
Anytime You Develop New Symptoms
Finally, earlier testing may be appropriate if you develop new symptoms during treatment. Always seek prompt medical advice from your prescribing clinician or, in urgent situations, contact a doctor or hospital. Blood testing can support that clinical assessment by providing objective data your doctor can review alongside your symptoms.

Frequently Asked Questions
Before starting a GLP-1 receptor agonist medication, prescribing clinicians typically request a baseline panel covering pancreatic enzymes (lipase, amylase), thyroid function (TSH), liver function (ALT, AST, GGT), kidney function (creatinine, eGFR), fasting glucose, HbA1c, lipid profile and a full blood count. The exact markers should always be confirmed with your prescriber. Our GLP-1 Readiness Blood Test ($199) covers all of these markers.
Most clinicians recommend bloodwork at 3 months after starting a GLP-1, then every 6 months once your dose is stable. Earlier testing is appropriate if you develop new symptoms (severe abdominal pain, persistent vomiting, fever) which can indicate pancreatitis or gallbladder issues. The GLP-1 Progress Blood Test is built for this check-in cadence. Always follow the schedule set by your prescribing clinician.
