Muscle Health

Measures CoQ10, a mitochondrial energy compound and antioxidant. Levels decline with age and drop significantly with statin use. For people investigating fatigue, muscle symptoms, or cardiovascular health.

Measures creatine kinase (CK), an enzyme that leaks from damaged muscle cells. Used to investigate muscle pain, statin side effects, rhabdomyolysis, and inflammatory muscle conditions.

Measures creatinine, a muscle metabolism waste product filtered by healthy kidneys. Elevated levels indicate impaired kidney filtration. Ordered alongside urea and eGFR as part of a kidney function panel.

Measures a single fasted serum growth hormone level to screen for GH deficiency or excess and assess pituitary function. Because GH is released in pulses, a single result is a screening baseline; formal diagnosis typically requires stimulation or suppression testing.

Measures IGF-1, a stable downstream marker of growth hormone produced by the liver. Used to investigate growth disorders in children, assess growth hormone deficiency or excess in adults, and monitor growth hormone therapy.

Measures LDH, an enzyme released when cells are damaged. Non-specific but useful for assessing haemolysis, liver conditions, certain cancers, and muscle damage. Best interpreted alongside more targeted tests.

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.

Measures myoglobin, a protein released from muscle cells when they are damaged. Used to investigate suspected rhabdomyolysis, severe muscle trauma, and as a supporting marker in cardiac investigations.

The Potassium Blood Test measures the main electrolyte inside cells, which controls heart rhythm, muscle contraction, and nerve transmission. Potassium is regulated by the kidneys and many common medications affect it, making monitoring important for people on diuretics, ACE inhibitors, or ARBs.

Measures magnesium inside red blood cells for a more accurate picture of tissue-level stores than serum testing. Preferred when deficiency symptoms persist despite a normal serum result. Available at Healius pathology centres.

Measures total testosterone, calculated free testosterone, and SHBG in a single blood draw. Used to investigate low testosterone in men and androgen excess in women. Morning collection required, as testosterone peaks in the early hours.

Measures plasma vitamin C (ascorbic acid), needed for collagen synthesis, immune function, iron absorption and antioxidant protection. Suboptimal levels are more common than many people assume, particularly in smokers, people with restricted diets and those under high physical or psychological stress.

Measures alpha-tocopherol (vitamin E) in blood. Vitamin E is a fat-soluble antioxidant protecting cell membranes and supporting immune and neurological function. Deficiency is uncommon with a balanced diet but can occur with fat malabsorption conditions, where prolonged deficiency may lead to peripheral neuropathy.
