THE PURSER WELLNESS REFERENCE
Understand your lab vocabulary.
Compare Dr. Purser’s adult ranges with your own report. Units, symptoms and health history matter when you discuss a result with your clinician.
15 entries
8-hydroxy-2-deoxyguanosine (8-OHdG) — lab reference
Urine/plasma method, creatinine correction, collection timing, and assay matter.
Specialty Wellness, Oxidative Stress, and Functional TestingAntioxidant Protection Assay (APA) — lab reference
Your APA report defines its own protection categories. Ask how your result relates to your current health and other findings.
Specialty Wellness, Oxidative Stress, and Functional TestingCatalase activity — lab reference
The method can change the result; ask what clinical question the test is meant to answer and whether a repeat would help.
Specialty Wellness, Oxidative Stress, and Functional TestingCMA intracellular micronutrient panel — lab reference
Your CMA report uses its own testing method and categories. Ask what a category means for you; this page does not set a personal severity level or treatment target.
Specialty Wellness, Oxidative Stress, and Functional TestingCytokine panel — lab reference
Ask your clinician to define genes/analytes, specimen, assay, repeatability, and how results change management.
Specialty Wellness, Oxidative Stress, and Functional TestingF2-isoprostanes — lab reference
Urine/plasma and mass-spec/immunoassay results are not interchangeable.
Specialty Wellness, Oxidative Stress, and Functional TestingGenetic variants / SNP findings — lab reference
Classify by evidence, zygosity, phenotype, and clinical actionability rather than a numeric range.
Specialty Wellness, Oxidative Stress, and Functional TestingGSH/GSSG ratio — lab reference
This ratio is useful only when both measurements were made using a reliable paired method.
Specialty Wellness, Oxidative Stress, and Functional TestingHeavy metals, blood or urine — lab reference
Specimen choice, timing, recent seafood/supplements, provoked vs unprovoked collection, and public-health thresholds matter.
Specialty Wellness, Oxidative Stress, and Functional TestingMyeloperoxidase (MPO) — lab reference
Assay and indication-specific.
Specialty Wellness, Oxidative Stress, and Functional TestingOxidized glutathione (GSSG) — lab reference
The test method and how the sample is protected after collection can affect this number.
Specialty Wellness, Oxidative Stress, and Functional TestingOxidized LDL — lab reference
Ask your clinician to use exact laboratory interval. Clinical utility and treatment targets are not universally standardized.
Specialty Wellness, Oxidative Stress, and Functional TestingReduced glutathione (GSH) — lab reference
Ask your clinician to specify whole blood, RBC, plasma, or intracellular method. Preanalytic handling is critical.
Specialty Wellness, Oxidative Stress, and Functional TestingSuperoxide dismutase activity — lab reference
RBC, plasma, and cellular assays are not interchangeable.
Specialty Wellness, Oxidative Stress, and Functional TestingTMAO — lab reference
Diet, kidney function, microbiome, timing, and assay affect results.
