URINALYSIS What is it? Urinalysis is the testing of urine. Reagent strips can test for the presence of blood, protein and other analytes from freshly voided urine (Wells, 1997) Why are they used? The composition of urine can change dramatically as a result of disease processes. It may contain red blood cells, glucose, proteins, white cells or bile. The presence of such abnormalities in urine is a warning sign of illness and maybe helpful in clinical assessment in the following ways: To determine the individuals urine status on admission as a baseline for comparisons with future assessments. To monitor changes in urinary constituents as a response to medication. To be used as a screening test to gather information about physical status. Indications for use Pre-screening and pre-operative assessment. All patients admitted to hospital within 24 hours of arrival. On recognition of any or all of the following clinical signs/symptoms i.e. urinary tract infection symptoms – burning sensation, offensive smelling odour, pain, pyrexia, cloudy urine. Please ensure you refer to local policy before undertaking any procedure Interpretation of results pH. The normal pH of urine varies from 4.5 – 8. It reflects the acid base balance of the body (Wells 1997). Protein. A morning specimen is recommended to ensure sufficient concentration of urinary protein. Protein in the urine can indicate a range of conditions, including renal disease, urinary tract infection (UTI), hypertension, pre-eclampsia, or congestive cardiac failure (Cook1996). Glucose. Glucose is not normally found in urine. Glycosuria is often indicative but never diagnostic of diabetes mellitus. Glycosuria in a patient with diabetes usually indicates poorly controlled diabetes. It can also be associated with Cushing’s syndrome and acute pancreatitis (Wells 1997, Cook 1996). Ketones. The ketones are the product of the breakdown of fatty acids. They are abnormal constituents of urine. Their presence may indicate dehydration, starvation or in combination with glucose in a person known to have diabetes, uncontrolled diabetes mellitus (Cook 1996). Blood/Haemoglobin. The presence of blood is a potentially serious sign (Lloyd 1993), especially when there are no other symptoms present such as pain. Blood in the urine may be due to one of four principle causes, trauma, infection, tumour or renal stones. It is common in the presence of a UTI. False positives may occur from containers contaminated with bleach or from the use of stale urine. N.B: In women the test for blood may be falsified from three days before to three days after menstruating. It is therefore not advisable to perform the test at this time (Roche Diagnostics Limited 2001) Please ensure you refer to local policy before undertaking any procedure Taken from the Trust Wide Nursing Guideline for Urine Testing UHCW 2008.
