When a clean catch midstream urine sample is collected the individual must clean area around the opening of the urethra and pass some urine into toilet before collecting the sample This urine sample will have characteristics similar to the urine that was present in the urinary bladder avoiding outside contaminants that usually would be found in the sample if the individual just urinated into the cup without performing the cleaning procedure The results of a urinalysis for this clean catch midstream sample can give good information about a patient s health Leucocytes white blood cells are an indication of a urinary tract bacterial infection Nitrites usually indicate the presence of bacteria and are a sign of urinary tract infection Urobilinogen is a waste product produced when hemoglobin is broken down and is a normal component of urine This material causes the urine to have a yellow color Protein is rarely found in the urine sample and its presence can be triggered by elevated blood pressure strenuous physical activity or severe kidney disease pH refers to how acidic the urine is and is controlled mostly by diet but can also be affected by intense physical activity pH tends to increase as the individual consumes less meat and animal products Using the information and the results of the urinalyses above indicate the sample letter that would likely be associated with an individual who Has a urinary tract infection Has diabetes mellitus inability to properly use glucose Is in renal kidney failure Just finished running a marathon Is a vegan strict vegetarian Blood presence of red blood cells in a clean catch urine sample indicates bleeding within the urinary tract caused by urinary stones calculi urinary tract infection or trauma to the urinary organ Specific gravity indicates how concentrated the urine sample is based upon how much water is present in comparison to the other materials in the sample The higher the specific gravity the less water the sample contains and the more concentrated the urine is Ketones are produced as an energy source when the individual has exhausted other energy sources in the body Any amount other that a trace i e tiny amount is an uncommon finding in the urine and can be present due to abnormal cellular use of glucose extreme physical exertion or lack of adequate food consumption e g starvation Bilirubin is a waste product from the breakdown of hemoglobin Its presence in the urine is an abnormal finding and could indicate excessive destruction of RBCs or abnormal liver function Glucose is an abnormal finding in the urine and indicates an elevated blood sugar level
