Reference Range

Please contact the duty biochemist for age/sex related reference ranges/ 0121 371 6543

Turnaround Time: 1 week

Related Tests Androstenedione

Digoxin

Reference Range

Therapeutic Range: 0.8-2.0 ug/L

Turnaround Time: 1 day

Urine Electrolytes

Reference Range

None Given. The results must be interpreted together with serum electrolytes and clinical details.

Turnaround Time: < 1 day

Urine Osmolality

Reference Range

None Given

Turnaround Time: 1 Day (Please contact the laboratory if urgent)

This is a screening test for the presence of diuretics in plasma or urine. As such, we will report results as Positive or Negative for the drugs listed above. All can be detected reliably at concentrations of 0.5 mg/L in urine and plasma.

Turnaround Time: 24 hours

Related Tests Potassium (serum) Sodium

Urine Protein:Creatinine ratio (Random urine)

Reference Range

<15 mg/mmol Creatinine = Normal
15 – 49 mg/mmol Creatinine = Trace Proteinuria. Consider ACEI or ARB in diabetes.
50 – 99 mg/mmol Creatinine = Significant proteinuria. Repeat using early am sample. Consider ACEI or ARB in hypertension.
100 – 300 mg/mmol Creatinine = High proteinuria. If new finding, seek nephrology advice regardless of eGFR.
>300 mg/mmol Creatinine = “Nephrotic range” proteinuria. If new finding, seek nephrology advice regardless of eGFR.

Proteinuria is a risk factor for cardiovascular disease and for decline in GFR in CKD

UK CKD Guidelines suggest if PCR is >100 mg/mmol patient should be referred to Nephrologists irrespective of GFR.

Source of Reference Range: NICE guideline CG73 (2008) and UK eCKD guidelines 2009.)
