Alb/Creat Ratio, Urine

A microalbumin creatinine ratio urine test checks the levels of the protein albumin in your urine (pee). Abnormal amounts of this protein may be an early sign of kidney disease.

  • Diabetes Comorbidity Assessment 023400

    11 analytes · Serum · No fasting · Turnaround Within 1 day

    Method and collection
    Method
    Lipid Profile With Non‐HDL Cholesterol: See individual tests. Kidney Profile ‐ creatinine: kinetic jaffe. Albumin: immunoturbidimetric
    Preparation
    Patient should be on a stable diet, ideally for two to three weeks prior to collection of blood. Fasting is not necessary for this profile, however fasting for 12 to 14 hours prior to collection of the specimen is recommended where the triglyceride value provides a priori diagnostic information such as screening for familial hypercholesterolemia or early onset heart disease, pancreatitis, or confirming hypertriglyceridemia.
    Collection
    Separate serum or plasma from cells within 45 minutes of collection. Lipid panels are best avoided for up to three months following acute myocardial infarction, although cholesterol can be measured in the first 24 hours. Collect random urine without preservatives. pH must be 4 to 8.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
