Let’s explore “Urine protein/creatinine ratio — lab reference”

≥75 increased; ≥125 commonly treated as a risk-enhancing level. Units are not directly interchangeable with mg/dL.

≥2 suggests higher cardiovascular risk; >10 may reflect acute inflammation and should generally be repeated when well.

Age, kidney function, obesity, rhythm, and clinical setting affect interpretation.

Use assay- and indication-specific rule-out/rule-in thresholds.

Advanced lipoprotein testing. Use the performing laboratory classification.

Method, units, and cutoffs vary. Dr. Purser to decide whether to retain.

Morning fasting collection is preferred when practical. Day-to-day variation is substantial.

Interpret with iron, transferrin saturation, and ferritin.

Negative acute-phase reactant; affected by liver function and nutrition.

Calculated from iron and TIBC. Fasting and timing improve consistency.

Acute-phase reactant. Menstruation, menopause, inflammation, liver disease, and iron therapy matter.

<150 supports deficiency; 150-400 is often treated as borderline and may warrant MMA/homocysteine review.
