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 changes in the MTHFR gene that affect how your body processes folate and vitamin B12. Certain variants may be linked to higher homocysteine levels, which can influence heart health, energy, fertility, and mood, while normal results suggest your folate metabolism is working as expected.

Detect muscle damage with our Myoglobin Blood 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 collection centres.

The Sodium Blood Test measures the level of sodium, an electrolyte that helps control fluid balance, blood pressure, and muscle and nerve function. Abnormal levels may suggest dehydration, kidney problems, or issues with hormone balance.

The Total Cholesterol Blood Test measures the overall amount of cholesterol in your blood. Cholesterol is needed for building cells and hormones, but too much can raise the risk of heart disease and stroke. This test helps check heart and metabolic health, especially when combined with other lipid tests.

The Triglycerides Blood Test measures the level of fats (triglycerides) in your blood. High levels can increase the risk of heart disease, stroke, and pancreatitis, and are often linked to diet, weight, and diabetes. Healthy levels support good heart and metabolic health.

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.

The Vitamin B1 (Thiamine) Blood Test measures levels of thiamine, a vitamin that helps your body convert food into energy and supports nerve and heart function. Low B1 can cause fatigue, muscle weakness, nerve problems, and in severe cases heart complications. Adequate levels are important for energy and overall health.
