Urinalysis comprises physical, chemical, and microscopic examination of urine. Although widely available, this test is often underused and misinterpreted. Urinalysis can provide helpful clues in. Clinical urine tests are examinations of the physical and chemical properties of urine and its microscopic appearance to aid in medical diagnosis. The term urinalysis—a blend of the words urine and analysis —generally refers to the gross examination of the urine, chemical evaluation using urine test strips, and microscopic examination.Urine examination targets parameters that can be. Microscopic examination, which identifies and counts the type of cells, casts, crystals, and other components such as bacteria and mucus that can be present in urine. Note: The microscopic examination is only done when the visual (macroscopi) findings are abnormal or when a doctor or nurse specifically asks for it
The microscopic examination of urine sediment is a common diagnostic tool taught to medical students, medical technologists, and others. The urine microscopic exam is difficult to teach because supervised instruction and textbook-based teaching suffer from numerous drawbacks Technique of Microscopic Examination of Urine Deposits 1-Centrifuge at least 5 to 10 ml of fresh urine, (crystals, blood, pus, and casts require only a few minutes, but if bacteria are being. How to Prepare Urine for Microscopic Examination. Place 5 to 10 mL of urine in a clean centrifuge tube (this volume needs to be constant for every UA or the number of cells, crystals, and casts will be influenced). Centrifuge urine at 1500 rpm for 5 minutes (Figure 3) The microscopic examination of urine sediment crystals is performed to confirm the presence and type of crystals in the sediment. Crystals are formed from salts in the urine. A wide variety of crystals can be found in normal urine and for the most part are clinically insignificant . You may require additional tests if your urine sample has any of the following substances at above-average levels. Red blood cells (RBC): Erythrocytes or Red blood cells in urine may indicate

Pyuria can be detected even if the urine sample contains damaged or lysed WBC's. A negative leukocyte esterase test means that an infection is unlikely and that, without additional evidence of urinary tract infection, microscopic exam and/or urine culture need not be done to rule out significant bacteriuria Microscopic hematuria may be discovered as an incidental finding on an urinalysis prompted by urinary or other symptoms. Urinary dipstick — The most common screening test for hematuria is the urinary dipstick test for blood. Dipsticks for hemoglobin are as sensitive as the urine sediment examination, but result in more false-positive tests Nitrites are found in the urine when nitrate, a substance normally present in urine, is converted to nitrites by the action of enzymes produced by gram-negative bacteria. Nitrites produce a chemical reaction in the reagent strip. A positive reagent test result should be verified by microscopic examination, or urine culture and sensitivity tests.
A comparative study of microscopic examination of 10 μl (simplified loop technique) and 50 μl (traditional drop technique) of uncentrifuged Gram-stained urine specimens for detection of significant bacteriuria was carried out. The results demonstrated that the 10-μl loop technique can be used as an alternative to the 50-μl drop technique for presumptive diagnosis of urinary-tract infection. Explain the importance of the microscopic examination. Describe the correct preparation of the urine sediment. Recognize cells, casts, bacteria, yeast, crystals, and other structures that may be present in urine sediment. Recognize artifacts in urine sediment and distinguish from significant findings Microscopic Examination. Microscopic examination is done after centrifuging the urine sample for about 3-5 minutes. The supernatant fluid is discarded and the underlying sediment is observed under microscope. It is checked for parameters like cells, casts, crystals and living organisms. Normal/Few Hyaline Cast Microscopic examination. Precautions. Urine must be analyzed within one hour of collection if held at room temperature. Keep urine at 2 to 8°C if delayed >8 hours. If urine is kept for a longer time, then it will get a false positive test like nitrite will be positive. Urea producing organisms will degrade urea to ammonia and change the pH to.

The sediment is usually examined using brightfield microscopy and subdued light (some structures will be missed if there is too much light in the field). Fine focus throughout the examination is used to identify structures in different focal planes The criteria for the reflex of urine specimens from urinalysis to microscopic exam (UA reflex to micro, UAR) and urinalysis to culture (UA reflex to culture, UARWC) will be changed. Current criteria: UA reflex to microscopic exam (SMH): Positive leukocyte esterase, protein OR blood
Microscopic examination/urine sediment. WBCs, RBCs, epithelial cells, and, rarely, tumor cells are the cellular elements found in the urinary sediment. The number of WBCs considered normal is typically 2-5 WBCs/hpf or less. A high number of WBCs indicates infection, inflammation, or contamination Urinalysis is a valuable tool used to diagnose and monitor renal and urinary tract illnesses. Typically it is a moderate- to high-sample volume test for a general chemistry lab, representing up to 30% of all samples received.

Urinalysis: Microscopic exam of the urine. A microscopic examination of the urine may reveal many different disease conditions. The following tests are the usual components of the exam: Test: Microscopic Urine Exam: RBC's. Clinical Implications: This will detect the presence of RBC's in the urine. Normal is 0-3 RBC's Microscopic exam Another part of the examination involves viewing several drops of urine under the microscope. The doctor will look for signs of any of the following The initial determination of microscopic hematuria should be based on microscopic examination of urinary sediment from a freshly voided, clean-catch, midstream urine specimen At our institutions a complete UA consists of three components: 1) visual examination to evaluate the color and clarity of the urine, 2) chemical examination to detect abnormalities in the urine such as blood, protein, glucose, and indicators of bacterial infection (leukocyte esterase, nitrite), and 3) microscopic examination to identify. Therefore, even though the microscopic examination of the urine to detect the presence of leukocytes and bacteria is more time consuming and harder to perform than the reagent strip test (Downs 1999), the former may be performed safely at the farm, whereas the bacteriological examination, regarded as the reference method for diagnosing UTI.
