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.

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).

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.

Insulin resistance can lead to difficulty losing weight, distinct abdominal fat, fatigue, bloating and sugar cravings. Identifying insulin resistance early and committing to lifestyle changes can ultimately help the progression to diabetes.

This male hormone test measures key hormones that play an important role in athletic performance and fertility.

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.

Iron deficiency is the most common nutritional problem in the UK. 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.

C-reactive protein (CRP) is a protein made by the liver and secreted into the blood. It is often the first evidence of inflammation or an infection in the body. Its concentration increases in the blood within a few hours after the start of infection or other inflammatory injury.
