Introduction
Urinalysis dry chemistry generally refers to the dry chemical testing of urine. Urine dry chemical testing is a laboratory method used to analyze specific chemical components in urine. Urinary sediment refers to the solid materials that settle in urine. Dry chemical urine testing is typically performed by observing color changes in the reagent pads on a multistrip test strip, allowing for multiple parameters to be tested.
Urinalysis by dry chemistry generally refers to the dry chemical testing of urine. This is a laboratory method used to analyze specific chemical components in urine. Urine sediment refers to the solid materials that settle in urine. The detailed analysis is as follows:
1. Dry Chemical Testing of Urine
Dry chemical testing of urine typically involves assessing color changes in reagent strips with multiple test pads. It covers numerous parameters and allows preliminary evaluation of urinary tract infections, diabetes, and hepatobiliary diseases. For example, ketones and glucose levels help in the auxiliary diagnosis of diabetes; leukocytes, occult blood, and nitrite tests are used to detect the presence of red blood cells, white blood cells, and bacteria, aiding in the diagnosis of urinary tract infections; bilirubin levels assist in evaluating hepatobiliary disorders.
2. Urine Sediment
Urine sediment examination involves analyzing the precipitate formed after centrifuging a urine sample. This enables direct visualization of formed elements such as red blood cells, white blood cells, bacteria, crystals, and casts in the urine, thereby facilitating more accurate diagnosis.
Both methods are important for assessing and understanding kidney-related diseases. If abnormal results are found, it is essential to follow up with further evaluations under the guidance of a physician.
