Hepatitis C Antibody
A Hepatitis C Antibody (anti-HCV) test detects antibodies produced by the immune system in response to the hepatitis C virus. A positive result indicates exposure to the virus but does not distinguish between a current or past infection. Further testing is needed for confirmation.
Herb Pollen Panel (wx3)
The Herb Pollen Panel (wx3) identifies weed pollen sensitisation. Older adults may notice changes in allergy patterns and new sensitivities can develop at any age.
Histamine
Histamine blood testing assesses mast cell activity and can help explain allergic-type symptoms. For older adults, understanding histamine metabolism supports targeted symptom management.
Holotranscobalamin
Holotranscobalamin is the earliest indicator of B12 depletion and may be particularly relevant for older adults. As B12 absorption naturally declines with age, this test could help detect changes before standard B12 tests.
Homocysteine
Homocysteine levels may rise with age and are associated with cardiovascular and cognitive health. Regular monitoring supports heart and brain protection in later years.
INR
INR monitoring is especially important for older adults, who are more commonly on anticoagulant therapy and more sensitive to warfarin dose changes.
Immunoglobulin IgA
Immunoglobulin IgA assessment supports mucosal immunity evaluation. For older adults, immune function changes with age, and IgA levels provide insight into infection susceptibility.
Immunoglobulin IgG
Immunoglobulin G (IgG) is the most abundant antibody in your blood and plays a key role in long-term immune protection. As we age, immune function naturally changes, making IgG monitoring a valuable part of proactive health management.
Immunoglobulin IgM
Immunoglobulin M (IgM) is the first antibody produced when your body encounters a new infection. As immune function evolves with age, monitoring IgM levels can be a valuable tool for understanding how effectively your body responds to new health challenges.
Inhalation Allergy Panel
The Inhalation Allergy Panel provides comprehensive airborne allergen screening. For older adults, allergy symptoms can overlap with other respiratory conditions, making accurate allergen identification important.
Insulin (Fasting)
Insulin sensitivity naturally decreases with age. Monitoring fasting insulin supports early intervention and metabolic health maintenance in later years.
Interleukin-6 (IL-6)
IL-6 levels tend to increase with age and are associated with inflammageing. Monitoring supports management of age-related inflammation and its health effects.
Intrinsic Factor Antibodies
Intrinsic Factor Antibodies tests for autoimmune-related B12 malabsorption. Pernicious anaemia becomes more common with age, making this test particularly relevant for older adults with unexplained or persistent B12 deficiency.
Iodine
Iodine supports thyroid function and cognitive health, both of which can change with age. Regular monitoring helps maintain metabolic balance and mental clarity.
Iron (Serum)
Serum iron levels can change with age and dietary habits. Regular monitoring helps maintain adequate iron for energy and cognitive function in later life.
Irregular Antibody Screening
An irregular antibody screening test detects unexpected antibodies in your blood that may react against foreign red blood cells. These antibodies can develop after transfusions, pregnancies, or immune stimulation and are important to identify for transfusion and pregnancy safety.
LDH (Lactate Dehydrogenase)
LDH monitoring is valuable for older adults, as tissue repair capacity may decline with age. Regular testing helps track overall cellular health and supports early detection of age-related changes across multiple organ systems.
LDL Cholesterol
LDL cholesterol accumulates over a lifetime. Managing levels in later years is essential for preventing cardiovascular events and maintaining heart health as you age.
LDL/HDL Ratio
The LDL/HDL ratio is your LDL cholesterol divided by your HDL. A lower ratio is more favourable and becomes more relevant as cardiovascular risk rises with age. Learn what your value can mean.
LH (Luteinizing Hormone)
LH (Luteinizing Hormone) is involved in the regulation of reproductive hormones. In older adults, LH levels naturally change as part of the ageing process, and monitoring may help your healthcare provider assess hormonal balance alongside other markers.
Lactase Genotyping
Lactase Genotyping reveals your genetic capacity to digest lactose. Many older adults experience increasing dairy intolerance, and this test clarifies whether genetics plays a role.
Lactate
Lactate metabolism can change with age as cardiovascular and metabolic efficiency evolve. Monitoring supports awareness of tissue oxygenation and metabolic health.
Leptin
Leptin testing provides insight into appetite regulation. For older adults, understanding leptin function supports weight management during age-related metabolic changes.
Leukocyte Differential
LDH (lactate dehydrogenase) is an enzyme found in virtually all tissues of your body. When cells are damaged, more LDH may be released into the blood. The LDH value can therefore be an indication of tissue damage. As you age, your tissues' repair capacity may change.
