• Lamb (f88) IgE Measures IgE antibodies to lamb meat to check for allergic sensitization, including as part of testing for alpha-gal (red meat) allergy.
• Lamb (f88) IgG4 Measures IgG4 antibodies to lamb, which reflect exposure to lamb in your diet; their link to food-related symptoms is debated.
• Lamb's Quarters (Goose Foot) (w10) IgE Measures IgE antibodies to lamb's quarters weed pollen, a late-summer allergy trigger.
• Large VLDL-P Counts the largest VLDL particles, which carry a high amount of triglycerides and are associated with greater cardiovascular risk.
• Latex (k82) IgE Measures IgE antibodies to natural rubber latex to check for allergic sensitization that may explain reactions to gloves, balloons, or medical devices.
• Lauric, C12:0 A 12-carbon saturated fatty acid found in coconut and palm kernel oil, measured in serum fatty acid panels to look at diet and fat metabolism.
• Lauroleic, C12:1 A minor 12-carbon monounsaturated fatty acid measured in serum fatty acid panels that look at diet and how your body breaks fats down for energy.
• LDL Cholesterol, Calculated The 'bad' cholesterol that can build up in artery walls. A core marker used to assess cardiovascular disease risk.
• LDL/HDL Ratio Compares your 'bad' (LDL) to 'good' (HDL) cholesterol, offering a quick snapshot of cardiovascular risk balance.
• LDL Medium Measures medium-sized LDL particles by ion mobility, part of an advanced lipid profile that looks at the size and number of LDL particles.
• LDL Particle NumberLDL-P LDL particle number — counts your actual LDL ('bad' cholesterol) particles rather than just the cholesterol they carry, often a stronger cardiovascular risk indicator than standard LDL cholesterol.
• LDL Pattern A classification of your LDL particle size profile as pattern A (mostly large particles) or pattern B (mostly small, dense particles), from ion mobility testing.
• LDL Size Measures the average size of your LDL ('bad' cholesterol) particles; smaller, denser particles are considered more likely to contribute to artery plaque.
• LDL Small Measures small, dense LDL particles, a lipid subfraction associated with higher cardiovascular risk and insulin resistance.
• Lead, 24 Hour Measures lead in a 24-hour urine collection, used to look at lead excretion and to monitor treatment, though blood lead is the main test for exposure.
• Lead/Creatinine Ratio Lead in a random urine sample expressed relative to creatinine, which corrects for urine concentration, used to look at lead excretion and possible exposure.
• Lead (Venous) Measures lead levels in your blood, used to assess exposure to this toxic heavy metal.
• Lemon (f208) IgE Measures IgE antibodies to lemon to check for allergic sensitization that may explain reactions after eating lemon or citrus products.
• Lemon (f208) IgG4 Measures IgG4 antibodies to lemon, which reflect exposure to lemon in your diet; their link to food-related symptoms is debated.
• Lentils (f235) IgE Measures IgE antibodies to lentils to check for allergic sensitization that may explain reactions after eating lentils or other legumes.
