Final answer:
Before identifying crystals in a urine specimen, a physical examination and urinalysis should be performed using a dipstick or test strip. Abnormal results may require further analysis such as urine culture. The process of identifying crystals requires microscopic examination after these preliminary tests.
Step-by-step explanation:
Before attempting to identify crystals in a urine specimen, certain tests should be performed. Initially, a physical examination of the sample for characteristics such as color and odor can provide information. Urinalysis is a common method for testing urine specimens, often using a dipstick. This tool compares against a color key to identify various substances in the urine. Abnormal levels may suggest infection or other health concerns. The use of test strips is also common, but the results must be appropriately timed to prevent false negatives or false positives.
Though these tests provide important insights, the specificity and sensitivity associated with these test strips may be low. As a result, it is advisable to proceed with further analysis such as urine culture, especially if there are indications of urinary tract infections from the initial tests.
The process of identifying crystals in the urine involves microscopic examination after performing the above-mentioned preliminary tests.
