Dipstick tests for trace amounts of protein yield positive results at concentrations of 5 to 10 mg per dLlower than the threshold for clinically significant proteinuria.15 A result of 1+ corresponds to approximately 30 mg of protein per dL and is considered positive; 2+ corresponds to 100 mg per dL, 3+ to 300 mg per dL, and 4+ to 1,000 mg per dL.31,32 Dipstick urinalysis reliably can predict albuminuria with sensitivities and specificities of greater than 99 percent.4 Asymptomatic proteinuria is associated with significant renal disease in less than 1.5 percent of patients.4,33. Squamous epithelial cells are large and irregularly shaped, with a small nucleus and fine granular cytoplasm; their presence suggests contamination. In fact, a recent study1 found that contamination rates were similar in specimens obtained with and without prior cleansing (32 versus 29 percent).
