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
24-hour urine protein — lab reference
Collection completeness must be assessed.
Urinalysis and Urine Kidney MarkersBlood/hemoglobin, urine — lab reference
Ask your clinician to confirm with microscopy; exercise, menstruation, myoglobin, and hemolysis may interfere.
Urinalysis and Urine Kidney MarkersGlucose, urine — lab reference
Renal threshold, SGLT2 inhibitors, pregnancy, and hyperglycemia matter.
Urinalysis and Urine Kidney MarkersHyaline casts — lab reference
Small numbers may be nonspecific; other cast types require context.
Urinalysis and Urine Kidney MarkersKetones, urine — lab reference
Fasting, ketogenic diet, vomiting, and diabetes context matter.
Urinalysis and Urine Kidney MarkersLeukocyte esterase — lab reference
Ask your clinician to read this result with microscopy, symptoms, nitrite, and culture.
Urinalysis and Urine Kidney MarkersNitrite — lab reference
A negative result does not exclude UTI.
Urinalysis and Urine Kidney MarkersProtein, dipstick — lab reference
Dipstick is albumin-biased. Ask your clinician to confirm persistent findings with quantitative ratio.
Urinalysis and Urine Kidney MarkersRBC, microscopy — lab reference
Persistent microscopic hematuria requires risk-based evaluation.
Urinalysis and Urine Kidney MarkersSpecific gravity — lab reference
Hydration and concentrating ability affect result.
Urinalysis and Urine Kidney MarkersUrine albumin/creatinine ratio — lab reference
A1 <30; A2 30-300; A3 >300. Persistence ≥3 months matters for CKD classification.
Urinalysis and Urine Kidney MarkersUrine appearance — lab reference
Color and clarity are nonspecific; review medications, hydration, and sediment.
Urinalysis and Urine Kidney MarkersUrine pH — lab reference
Diet, infection, medications, and specimen age affect result.
Urinalysis and Urine Kidney MarkersUrine protein/creatinine ratio — lab reference
Ask your clinician to use laboratory and indication-specific thresholds; consider timed collection when needed.
Urinalysis and Urine Kidney MarkersWBC, microscopy — lab reference
Ask your clinician to read this result with symptoms, culture, contamination, and other sediment findings.
