  1. UA Chemistry

  2. Protein • Protein Error of Indicators pH 3False Positive Highly Buffered Alkaline urine Detergent (Ammonium compounds) Loss of Buffer • False NegativeProteins other than Albumin

  3. Protein • Sulfosalicylic Acid PrecipitationFalse Pos Radiographic Dye Sp Gr • Bence Jones Heat Prec. 60-100 then redisolve at 100 • Electrophoresis • Microalbuminuria Diabetic Screen

  4. ProteinClinical Significance • Prerenal Hemolysis, Muscle Injury, Multiple Myeloma, Infection • RenalGlomerularTubular • PostrenalUTI,Injury, Contamination

  5. ProteinClinical Significance • Protein is present in just about all renal diseases. • Expect a positive protein if Casts are in sediment. • Orthostatic Proteinuria
