Health Check (Simone Jamie)

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.

Calcium and vitamin D play a critical role in maintaining bone health. When you don’t get enough calcium, you increase your risk of developing osteoporosis and stress fractures. This blood test measures both your total calcium and corrected calcium levels, as well your 25-OHD vitamin D levels.

Blood glucose is generated from carbohydrates and to use this fuel for energy your body needs insulin. With type 2 diabetes the cells either ignore the insulin or the body doesn't produce enough of it. Glucose then builds up leading to problems with the heart, kidneys, eyes, nerves, and blood vessels.

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.

Your kidneys filter waste from your body and regulate salts in your blood. They also produce hormones and vitamins that direct cell activities in many organs and help to control blood pressure. When the kidneys aren't working properly, waste products and fluid can build up to dangerous levels creating a life-threatening situation.

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.

Reverse T3 (rT3) is virtually inactive having only 1% the activity of T3 and blocks the action of T3 acting as a metabolic break. Normal metabolism of T4 requires the appropriate balance of T3 to rT3. If the proportion of rT3 dominates then it will antagonise T3 thus producing hypothyroid symptoms despite sufficient circulating levels of T4 and T3.

In addition to screening for the thyroid hormones that play a key role in regulating metabolism, this advanced thyroid function test detects and measures the quantity of specific thyroid autoantibodies to determine whether autoimmune disease may be impacting thyroid function.

Homocysteine is an amino acid that’s regulated by the body’s methylation process, which supports detoxification, energy production, and nervous system health. If methylation is not functioning efficiently, homocysteine can build up, which may raise the risk of heart and and neurological issues.

Vitamin B12 is an essential vitamin found in meat products and certain algae such as seaweed. It helps maintain healthy nerve cells and red blood cells and is also needed to make DNA, the genetic material in all cells. Both high and low vitamin B12 blood test levels may indicate an underlying problem. Low levels can suggest anaemia, a parasite or hyperthyroidism, whilst high levels can be a sign of liver disease, diabetes or kidney failure.

Like vitamins, minerals are substances found in food that your body needs for growth and health. There are two kinds of minerals - macrominerals and trace minerals. Your body needs just small amounts of trace minerals which include iron, copper, zinc and selenium.
