Used primarily in urinalysis, the Urate Stain Kit (Sternheimer-Malbin Method) enables the differentiation of white blood cells, red blood cells, and various types of urinary casts and crystals in sediment samples. The stain helps enhance contrast and cellular detail under the microscope, allowing for more accurate identification of cellular elements in urine. It is especially useful in diagnosing and monitoring urinary tract infections, kidney diseases, and inflammatory conditions of the renal system. The method is commonly applied in clinical laboratories during routine microscopic examination of urine sediment to support assessment of renal and urinary tract health.
