The 17-Hydroxyprogesterone test measures the levels of a hormone called 17-hydroxyprogesterone in your blood. Produced by the adrenal glands, this hormone is a precursor in the synthesis of cortisol. The test is commonly used to diagnose congenital adrenal hyperplasia (CAH), a genetic condition that affects hormone production and can lead to an excess of 17-hydroxyprogesterone. Elevated levels can indicate CAH or other adrenal disorders, and further tests may be required to confirm a diagnosis and guide treatment.

The Activated Partial Thromboplastin Time (APTT) test measures how long it takes for your blood to clot. This test evaluates the function of several blood clotting factors in the intrinsic and common pathways of coagulation. Prolonged APTT can indicate bleeding disorders, the presence of inhibitors, or issues with blood clotting factors. It is often used to monitor patients on anticoagulant therapy or diagnose clotting disorders.

Adiponectin is a protein hormone secreted by fat cells (adipocytes) that plays a role in regulating glucose levels and fatty acid breakdown. Higher levels of adiponectin are associated with a lower risk of type 2 diabetes and cardiovascular disease. Low levels can indicate obesity, insulin resistance, or metabolic syndrome. Measuring adiponectin levels helps assess metabolic health and risk of related conditions.

Adjusted calcium is the total calcium level in the blood adjusted for the amount of albumin, a protein that can affect calcium levels. This measurement is important for evaluating calcium metabolism, particularly in cases where albumin levels are abnormal. It helps in diagnosing and managing conditions related to bone health, parathyroid function, and kidney function.

Alanine Aminotransferase (ALT) is an enzyme primarily found in the liver. It plays a role in amino acid metabolism. Elevated ALT levels in the blood can signal liver inflammation or damage, often due to conditions such as hepatitis, fatty liver disease, or alcohol abuse. This test is frequently used to monitor liver function and diagnose liver-related health issues.

Albumin is a protein produced by the liver that helps maintain blood volume and pressure by regulating the oncotic pressure of the blood. Low levels of albumin can suggest liver disease, kidney problems, or malnutrition. It is commonly measured to assess overall health, liver function, and nutritional status.

The alcohol test measures the concentration of ethanol in the blood. It is used to evaluate recent alcohol consumption and its potential effects on health. This test can be used in various settings, including clinical assessments for alcohol use disorders, accident investigations, and monitoring the impact of alcohol on health.

The aldolase test measures the level of the enzyme aldolase in the blood. Aldolase plays a role in the breakdown of glucose for energy. Elevated levels can indicate muscle damage or diseases such as muscular dystrophy, liver disease, or certain cancers. This test helps in diagnosing and monitoring these conditions.

Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium and potassium levels in the blood and maintain blood pressure. The aldosterone test is used to diagnose conditions like primary aldosteronism or adrenal insufficiency, which can lead to imbalances in electrolytes and blood pressure.

An allergy profile is a series of tests that measure specific immunoglobulin E (IgE) antibodies to identify allergens causing allergic reactions. This profile helps diagnose and manage allergies to substances like pollen, mould, pet dander, or foods.

Alpha-Fetoprotein (AFP) is a protein produced by the liver and yolk sac during fetal development. In adults, elevated levels can be a marker for liver cancer (hepatocellular carcinoma), germ cell tumours, or certain liver conditions. It is used for screening, diagnosis, and monitoring treatment response.
