Heart & Circulation

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.

The MTHFR Gene Test looks for variants in the MTHFR gene (C677T and A1298C) that can reduce the activity of an enzyme involved in folate metabolism and the recycling of homocysteine. Understanding your MTHFR status can help interpret your homocysteine, folate, and B12 levels.

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.

NutriSTAT looks at how your body is actually working, not just whether your numbers sit inside a reference range. One at-home collection kit covers metabolic function, thyroid markers, cardiovascular risk factors, hormones, essential minerals, toxic metals, fatty acids, amino acids, and organic acids.

The Omega-3 Complete test measures your full fatty acid profile from a finger-prick blood spot sample collected at home. It covers Omega-3, Omega-6, Omega-7, Omega-9 and saturated fatty acids, including the Omega-3 Index, Omega-6:3 ratio, AA:EPA ratio, and individual fatty acid percentages.

The Omega-3 Plus test measures three key fatty acid markers from a finger-prick blood spot sample collected at home: your Omega-3 Index, Omega-6:3 ratio, and AA:EPA ratio. These markers reflect the balance between pro-inflammatory and anti-inflammatory fatty acids in your body.

The Oral Microbiome Mapping test analyses the bacterial community in your saliva, identifying species present and flagging periodontal pathogens associated with gum disease and oral inflammation. Oral microbiome imbalances have been linked to systemic conditions including cardiovascular health and metabolic function.

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.

The Sodium Blood Test measures the main electrolyte in blood and body fluid, which the kidneys regulate to maintain fluid balance, blood pressure, and nerve and muscle function. Abnormal sodium levels can arise from dehydration, kidney disease, adrenal disorders, or certain medications, and it is routinely included in electrolyte and metabolic panels.

Measures all cholesterol-containing lipoproteins in a single reading (HDL, LDL and other particles combined). A broad cardiovascular health screen and practical starting point for people wanting a quick check or tracking whether overall cholesterol is trending in the right direction.

Measures fasting triglyceride levels in blood. Elevated triglycerides are associated with increased cardiovascular risk and are commonly linked to a diet high in refined carbohydrates and sugar, excessive alcohol intake, and insulin resistance.

Measures serum uric acid (urate), the end product of purine metabolism. Used to investigate gout, assess kidney stone risk, and monitor urate-lowering therapy. Elevated levels are also associated with metabolic syndrome and kidney disease.

Measures thiamine diphosphate (TDP), the active form of vitamin B1, in red blood cells. Thiamine is involved in converting carbohydrates into energy and is important for nerve and heart function. Deficiency is associated with heavy alcohol use, poor dietary intake and malabsorption conditions.
