and
Yellow top round bottom tube (no additive) Yellow top round bottom tube (no additive)
Minimum:
TWO 4 mL aliquots from a well-mixed random collection.
Absolute Minimum: 3 mL
Turn Around Time:
1-5 days upon receipt at reference laboratory
Reference Range:
Total Protein 10-140 mg/d Albumin, Urine Detected Alpha-1 Globulins, Urine None detected Alpha-2 Globulins, Urine None detected Beta Globulins, Urine None detected Gamma, Urine None detected Free Urinary Kappa Light Chains 0.14 - 2.42 mg/dL Free Urinary Kappa Excretion/Day By report Free Urinary Lambda Light Chain 0.02 - 0.67 mg/dL Free Urinary Lambda Excretion/Day By report Free Urinary Kappa/Lambda Ratio 2.04 - 10.37 (ratio) IFE Interpretation By report
Interpretive Data:
Total urinary protein is determined nephelometrically by adding the albumin and kappa and/or lambda light chains. This value may not agree with the total protein as determined by chemical methods, which characteristically underestimate urinary light chains.
Methodology:
Qualitative Immunofixation Electrophoresis/Quantitative Nephelometry
