Active Vitamin B12
The aPTT test measures how long it takes for your blood to clot. This clotting time provides insight into part of the clotting process. The test is often requested when using certain anticoagulant medications or before surgery. In older adults, blood clotting may change due to medication use or other conditions. Your doctor can assess the result and discuss what it means for you. The information on this page is intended as general information and is not a substitute for professional medical advice. Always discuss your results with a doctor.
Folate (Folic Acid)
Folate measures vitamin B9, a nutrient that may become harder to absorb as we age. For older adults, adequate folate levels could support cognitive function, cardiovascular health, and healthy red blood cell production.
Holotranscobalamin
AST (aspartate aminotransferase) is an enzyme found in your liver, heart, and muscles. When cells in these organs are damaged, the AST value in your blood may rise. The test is often requested alongside other liver enzymes. As you age, both the liver and heart may become more sensitive. Your doctor can evaluate the result in the context of your overall health.

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.
Methylmalonic Acid (MMA) (Blood)
MMA Blood measures a functional B12 marker that may be particularly informative for older adults. As B12 absorption and metabolism may change with age, MMA testing could reveal deficiencies not detected by standard B12 blood tests.
Methylmalonic Acid (MMA) (Urine)
MMA Urine provides a non-invasive assessment of functional B12 status, which may be especially convenient for older adults. This test can help detect cellular B12 deficiency without the need for a blood draw.
Vitamin A
Vitamin A measures retinol levels, a fat-soluble vitamin that may become increasingly important to monitor with age. Adequate vitamin A could support immune resilience, vision preservation, and skin health in older adults.
Vitamin B1 (Thiamine)
Vitamin B1 (thiamine) is considered important for energy metabolism, which may become less efficient with age. Some older adults may have reduced absorption. Monitoring levels can help healthcare providers support healthy ageing strategies.
Vitamin B12
Vitamin B12 is considered especially important for older adults, as absorption may decline with age. Low levels have been associated with cognitive changes and anaemia. Regular monitoring may help healthcare providers support healthy ageing.
Vitamin B2 (Riboflavin)
Vitamin B2 (riboflavin) is considered important for energy metabolism and antioxidant protection, which may be especially relevant for older adults. Absorption and dietary intake may change with age. Healthcare providers can help assess your needs.
Vitamin B3 (Niacin)
Bilirubin is a yellow substance released when old red blood cells break down. Your liver processes bilirubin and excretes it through bile. The bilirubin value can show how well your liver and bile ducts are functioning. An elevated bilirubin value may have various causes, such as liver conditions or bile duct problems. Your doctor can best assess the result. The information on this page is intended as general information and is not a substitute for professional medical advice. Always discuss your results with a doctor.
Vitamin B6
Vitamin B6 is considered important for cognitive function, immune health, and metabolism in older adults. Requirements may change with age, and some medications common in later life may affect B6 status. Healthcare providers can help assess your needs.
Vitamin B7 (Biotin)
Vitamin B7 (biotin) is considered important for maintaining hair, skin, and nail health in older adults. Age-related dietary changes may affect biotin intake. Healthcare providers can help assess whether your levels support healthy ageing.
Vitamin C
Vitamin C is considered especially important for older adults, as it may support immune function, wound healing, and antioxidant protection against age-related oxidative stress. Dietary intake may vary with changing eating patterns. Healthcare providers can help assess your needs.
Vitamin D (25-OH)
Vitamin D becomes increasingly important with age, supporting bone density, muscle strength, and immune resilience. Regular testing can help maintain mobility and quality of life as you age.
Vitamin E
Vitamin E supports healthy ageing by protecting cells from oxidative damage. Maintaining adequate levels may contribute to cognitive health and cardiovascular well-being as you age.
Vitamin K1
The ESR value (erythrocyte sedimentation rate) measures how quickly your red blood cells settle to the bottom of a tube. A higher sedimentation rate may indicate inflammation or infection somewhere in your body. The ESR value typically increases slightly with age. Your doctor can distinguish between a normal age-related change and a value that needs attention.
