Just another cool lil test in the lab! 🤓 The Sulfosalicylic Acid (SSA) Test 🔬 Some facilities use this as a confirmatory test for protein in urine. When 3% SSA is added, proteins precipitate, and the sample turns cloudy. The more cloudiness, the more protein present. Unlike the standard dipstick, which mainly detects albumin, the SSA test picks up all proteins, including globulins and Bence Jones proteins (important in multiple myeloma). It’s a simple, old-school test, but it tells you a lot.
