• Perfluorodecanoic AcidPFDA Measures perfluorodecanoic acid (PFDA), a long-chain 'forever chemical,' in your blood to help gauge your past and ongoing exposure to PFAS compounds.
• Perfluorohexanesulfonic AcidPFHxS Measures perfluorohexanesulfonic acid (PFHxS), a persistent 'forever chemical,' in your blood to help gauge your exposure to PFAS from water, products and the environment.
• Perfluoromethylheptane Sulfonic Acid IsomersSm-PFOS Measures the branched forms of PFOS (Sm-PFOS) in your blood, part of assessing your overall exposure to PFOS and other 'forever chemicals.'
• Perfluorononanoic AcidPFNA Measures perfluorononanoic acid (PFNA), a persistent 'forever chemical,' in your blood to help gauge your exposure to PFAS compounds from the environment.
• Perfluorooctane Sulfonic AcidPFOS Measures perfluorooctane sulfonic acid (PFOS), one of the most studied 'forever chemicals,' in your blood to help gauge your long-term exposure to PFAS.
• Perfluorooctanoic Acid IsomersSb-PFOA Measures the branched forms of PFOA (Sb-PFOA) in your blood, part of assessing your overall exposure to PFOA and other 'forever chemicals.'
• Perfluorooctanoic AcidPFOA Measures perfluorooctanoic acid (PFOA), a well-studied 'forever chemical' once used in non-stick coatings, in your blood to help gauge your PFAS exposure.
• Perfluoroundecanoic AcidPFUnDA Measures perfluoroundecanoic acid (PFUnDA), a long-chain 'forever chemical,' in your blood to help gauge your exposure to PFAS compounds.
• Persimmon (kaki Fruit) (f301) IgE Measures IgE antibodies to persimmon (kaki fruit), a food allergen, to check whether your immune system is sensitized to this fruit.
• pH Measures how acidic or alkaline your urine is, a routine part of urinalysis that can reflect diet, kidney handling of acid, and some infections.
• Phoma betae (m13) IgE Measures IgE antibodies to Phoma betae, an outdoor mould found on plants, to check whether you are sensitized to this mould.
• Phosphate, 24 Hour Measures the total phosphate your kidneys excrete in urine over 24 hours, helping assess phosphate balance, kidney handling and kidney stone risk.
• Phosphate/Creatinine Ratio A ratio calculated from urine phosphate and urine creatinine, used to judge phosphate excretion while adjusting for how concentrated the urine is.
• Phosphate, Random Measures phosphate in a single random urine sample, giving a snapshot of how much phosphate your kidneys are excreting.
• Phosphatidylserine/ Prothrombin Antibody (IgG) Measures IgG antibodies against the phosphatidylserine/prothrombin complex, used alongside other antiphospholipid tests when looking at clotting or pregnancy-loss risk.
• Phosphatidylserine/ Prothrombin Antibody (IgM) Measures IgM antibodies against the phosphatidylserine/prothrombin complex, used alongside other antiphospholipid tests when looking at clotting or pregnancy-loss risk.
• Phosphorus Measures phosphorus, a mineral important for bone health, energy production, and cell function, closely regulated alongside calcium.
• Phosphorylated Tau 181 (p-tau181)pTau-181 A blood-based marker of a protein involved in Alzheimer's disease pathology. An emerging tool being used to help assess Alzheimer's risk.
• Phosphorylated Tau 217 (p-tau217) Measures phosphorylated tau 217 in plasma, a blood marker linked to the brain changes of Alzheimer's disease, used in people with memory symptoms.
• Phthalic Anhydride (k79) IgE Measures IgE antibodies to phthalic anhydride, an industrial chemical, to check for sensitization that may underlie work-related asthma or rhinitis.
