• Insulin Autoantibody An autoantibody that targets insulin. Used along with other markers to help diagnose type 1 diabetes.
• Insulin, Human (c73) IgE Measures IgE antibodies to human insulin to check for allergic sensitization in people who use insulin and have had reactions to it.
• Insulin, Intact, Lc/Ms/Ms Measures intact insulin in serum using LC/MS/MS (mass spectrometry), a highly specific method, to help assess insulin resistance and how your body regulates blood sugar.
• Insulin-Like Growth Factor 1 (IGF-1), LC/MSIGF-1 Insulin-like growth factor 1, a hormone that reflects your average growth hormone activity over time. Used to evaluate growth hormone excess or deficiency.
• Insulin Resistance Score A calculated score estimating insulin resistance, derived from fasting intact insulin and C-peptide measured by mass spectrometry, used to help assess metabolic and diabetes risk.
• Interleukin-10IL-10 An anti-inflammatory signaling protein (cytokine). Studied as part of broader inflammatory or immune panels.
• Interleukin 1 Beta Measures interleukin-1 beta, a signalling protein that drives inflammation, used mostly in specialised settings to look at inflammatory and autoinflammatory conditions.
• Interleukin-4IL-4 A signaling protein (cytokine) involved in allergic and immune responses. Studied as part of broader inflammatory or immune panels.
• Interleukin-6IL-6 A key inflammatory signaling protein (cytokine). Elevated levels reflect active inflammation and are linked to cardiovascular and metabolic risk.
• Interleukin-8 (IL-8), PlasmaIL-8 A signaling protein (cytokine) involved in inflammation, particularly in recruiting immune cells. Studied as part of broader inflammatory panels.
• International Normalized RatioINR International Normalized Ratio, a standardized measure of blood clotting time. Mainly used to monitor patients on the blood thinner warfarin.
• Intestinal Isoenzymes The intestinal fraction of alkaline phosphatase, measured in serum to help work out whether a raised alkaline phosphatase comes from the intestine rather than liver or bone.
• Intrinsic Factor Blocking Antibody Measures antibodies that block intrinsic factor, a protein needed to absorb vitamin B12, used to help evaluate pernicious anemia as a cause of B12 deficiency.
• Iodine Measures iodine levels, an essential mineral your thyroid needs to make thyroid hormones.
• Iodine, Random Measures iodine in a single urine sample, reflecting your recent iodine intake from diet, supplements, or other sources such as contrast dyes.
• Iron % Saturation The percentage of transferrin (your iron-carrying protein) that's currently occupied by iron — a key marker for detecting iron deficiency or overload.
• Iron, Total Measures the iron circulating in your blood, used along with other markers (like ferritin and TIBC) to evaluate for iron deficiency or overload.
• Isocyanate HDI (k77) IgE Measures IgE antibodies to the isocyanate HDI, a chemical used in paints and coatings, to check for sensitization in people with work-related breathing symptoms.
• Isocyanate MDI (k76) IgE Measures IgE antibodies to the isocyanate MDI, a chemical used in foams, adhesives, and insulation, to check for sensitization in people with work-related breathing symptoms.
• Isocyanate TDI (k75) IgE Measures IgE antibodies to the isocyanate TDI, a chemical used in flexible foams and coatings, to check for sensitization in people with work-related breathing symptoms.
