The Growth Hormone (GH) Blood Test measures a hormone that controls growth, muscle mass, and how your body uses fat and sugar. Abnormal levels can affect height in children, muscle strength, energy, and metabolism in adults.

The Lactate Dehydrogenase (LDH) Test measures an enzyme found in many tissues, including the heart, liver, muscles, and blood cells. High LDH levels may be linked to tissue damage, liver or muscle disease, or certain cancers, while normal levels usually indicate healthy cell function.

The Magnesium Blood Test measures magnesium, a mineral essential for energy production, nerve function, and healthy muscles and bones. Low magnesium may be linked to cramps, fatigue, or irregular heartbeat, while healthy levels support strong muscles, steady energy, and heart health.

Detect muscle damage with our Myoglobin test. This important analysis measures myoglobin levels to identify acute muscle injury, assess rhabdomyolysis risk, evaluate heart muscle damage, and monitor muscle breakdown in various medical conditions.

The Potassium Blood Test measures potassium, a mineral and electrolyte that helps control muscle movement, nerve signals, and heart rhythm. Abnormal levels may suggest kidney problems, hormone imbalances, or issues with diet and medications.

The Red Blood Cell Magnesium Blood Test measures magnesium stored inside red blood cells, giving a more accurate picture of long-term magnesium status than a standard blood test. Magnesium is vital for energy, muscle function, heart rhythm, and nerve health. Low levels may cause cramps, fatigue, or heart problems.

This test is only available at Healius and 4Cyte collection centres.

The Rheumatoid Factor (RF) Blood Test checks for an antibody that can be present when the immune system attacks healthy tissues. Higher levels are often linked to rheumatoid arthritis and other autoimmune diseases that cause joint pain, swelling, and stiffness.

The Ross River Virus (RRV) Serology Test checks for antibodies your body makes after infection with Ross River virus, which is spread by mosquitoes in Australia. This test may help confirm exposure if you have symptoms such as joint pain, fever, tiredness, or rash.

The Urate (Uric Acid) Blood Test measures the level of uric acid in your blood. High levels can cause crystals to form in the joints, leading to gout, and may also signal kidney problems or higher risk of heart disease. Low levels are less common but can happen with certain conditions or medications.
