The CRP Blood Test measures C-reactive protein, which rises in the blood with inflammation. High CRP levels can suggest infection, injury, or chronic inflammatory conditions, while lower levels are linked with healthier immune and heart function.

The Creatine Kinase (CK) Blood Test measures an enzyme found in muscles, the brain, and the heart. High CK levels can signal muscle injury, intense exercise, or conditions affecting the heart and nervous system, while normal levels support healthy muscle and energy function.

Monitor your blood clotting function with our Fibrinogen blood test. This important analysis measures fibrinogen levels, a crucial protein involved in blood clot formation, providing insights into bleeding disorders, cardiovascular risk, and inflammatory conditions that may affect your clotting system.

The Full Blood Count (FBC) Blood Test measures your blood's red cells, white cells, and platelets. It may help check for anaemia, infection, immune problems, or overall health changes, and is one of the most commonly requested routine blood tests. This test also includes ESR.

The High-Sensitivity CRP (hs-CRP) Blood Test measures very small amounts of C-reactive protein, a marker of inflammation in the body. Higher hs-CRP levels can be linked to a greater risk of heart disease, stroke, or chronic inflammation, while lower levels suggest healthier cardiovascular and immune function.

The Homocysteine Blood Test measures levels of homocysteine, an amino acid in the blood. High levels can be linked to heart disease, stroke, and vitamin deficiencies (B6, B12, or folate), while healthy levels support circulation, metabolism, and brain health.

The Immunoglobulin A (IgA) test measures antibodies that protect mucous membranes in the respiratory and digestive tracts. Abnormal IgA levels can indicate immune deficiencies, chronic infections, or autoimmune conditions such as coeliac disease.

The Immunoglobulin D (IgD) test measures a rare type of antibody involved in initiating immune responses. Abnormal IgD levels can be linked to certain immune disorders, chronic infections, and some inflammatory or autoimmune conditions.

The Immunoglobulin E (IgE) test measures the amount of IgE antibodies in the blood. IgE plays a key role in allergic reactions, triggering the release of histamine and other chemicals when the body encounters allergens such as pollen, dust, or certain foods. Elevated IgE levels can indicate allergic conditions like hay fever, asthma, or eczema, and may also occur in some parasitic infections. This test helps identify potential allergic triggers and supports the diagnosis of allergy-related disorders.

Investigate immune-mediated inflammation with our Immunoglobulin G4 (IgG4) test. This specialised analysis measures IgG4 levels to diagnose IgG4-related disease, assess chronic inflammatory conditions, and evaluate immune tolerance mechanisms affecting multiple organ systems.

Detect early immune responses with our Immunoglobulin M (IgM) Test. This important analysis measures IgM levels to identify recent infections, assess primary immune function, and evaluate your body's first-line antibody response to pathogens and immune challenges.

The Iron Studies Blood Test (including ferritin) measures iron levels and how well your body stores and uses iron. Low iron may be linked to anaemia, fatigue, or poor concentration, while high levels may point to iron overload or inflammation.

The CA-125 Blood Test measures a protein that can rise in the blood with ovarian cancer and certain non-cancer conditions. This test may help monitor ovarian health, especially if you have symptoms, known risk factors, or are being followed up after treatment. It is usually used alongside other checks rather than as a stand-alone cancer test.

The Reverse T3 (rT3) Test measures a form of thyroid hormone that is inactive. High rT3 levels may happen during stress, illness, or inflammation when the body slows metabolism. This test may help give a broader picture of thyroid and metabolic function alongside a Thyroid Function Tests (TSH, T3, and T4).

The Rheumatoid Factor (RF) Blood Test checks for an antibody that can be present when the immune system attacks healthy tissues. Higher levels are often linked to rheumatoid arthritis and other autoimmune diseases that cause joint pain, swelling, and stiffness.

The Ross River Virus (RRV) Serology Test checks for antibodies your body makes after infection with Ross River virus, which is spread by mosquitoes in Australia. This test may help confirm exposure if you have symptoms such as joint pain, fever, tiredness, or rash.
