Insulin resistance is a condition where cells fail to respond to the normal actions of insulin which is produced by the pancreas. When the body produces insulin under conditions of insulin resistance, the cells in the body are resistant to the insulin and are unable to use it as effectively. This can lead to high blood sugar and pancreatic dysfunction.

Lipids and cholesterol are fat-like substances in your blood. Some are necessary for good health, but when you have a high level of cholesterol in your blood, a lot of it ends up being deposited in the walls of your arteries and other vital organs. Lifestyle choices including diet, exercise and alcohol intake can all influence cholesterol levels and your risk of developing heart disease.

Vitamin D is essential for bone strength as it helps the intestines absorb calcium. Calcium and vitamin D play a critical role in developing and maintaining your overall bone health, and when you don’t get enough you increase your risk of developing osteoporosis and the incidence of stress fractures.

The full blood count is used as a broad screening test to check for such disorders as anaemia (decrease in red blood cells or haemoglobin), infection, and many other diseases. It is actually a group of tests that examine different parts of the blood. Results from the following tests provide the broadest picture of your health.

Your liver processes drugs and alcohol, filters toxic chemicals, stores vitamins and minerals, and makes bile, proteins and enzymes. This liver function test examines enzymes and other markers for evidence of damage to your liver cells or a blockage near your liver which can impair its function.

A blood test is used to find out the level of waste products in your blood and calculate what’s called your estimated glomerular filtration rate (eGFR).

The hsCRP test is a highly sensitive quantification of CRP, a protein released into the blood by the liver during inflammation, and has been associated with the presence of heart disease.

Elevated homocysteine blood test levels are a risk factor for cardiovascular disease, and may also be elevated in cases of malnutrition or vitamin B12 or folate deficiency.

Iron deficiency is the most common nutritional problem in Australia. It slows your body’s production of haemoglobin, which your red blood cells need to pick up oxygen from your lungs and carry it to every cell in your body. If you have a shortage of iron you experience symptoms of anaemia, which include feeling breathless after little exercise, feeling tired, heart palpitations and looking pale.

Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.
