The urine dipstick detects albumin primarily. Albuminuria is seen in glomerular proteinuria. False-positive results can occur with recently exposure to iodinated radiocontrast agents, alkaline urine, and gross hematuria. SSA detects all proteins, not just albumin.  Proteinuria involving non-albumin proteins as well as albumin is seen more in tubular or overflow proteinuria. Iodinated radiocontrast also will interfere with the accuracy of the SSA test.
