Abnormal findings on microbiological examination of urine
A microbiological examination of urine is a laboratory test that is performed to identify and quantify microorganisms in a patient's urine sample. The presence of microorganisms in urine can indicate the presence of an infection in the urinary tract. In some cases, the microbiological examination may reveal abnormal findings that require further investigation and treatment.
- Positive culture: A positive culture indicates the presence of microorganisms in urine. The most common microorganisms that cause urinary tract infections are bacteria such as Escherichia coli, Klebsiella pneumoniae, and Staphylococcus saprophyticus. A positive culture may also indicate the presence of fungi or viruses, which are less common causes of urinary tract infections.
- High colony count: A high colony count of a specific microorganism may indicate a significant infection. The colony count is the number of microorganisms present in a unit of urine, usually expressed as colony-forming units per milliliter (CFU/mL). A colony count of 100,000 CFU/mL or higher is considered significant for a urinary tract infection.
- Antibiotic resistance: Microorganisms that are resistant to antibiotics may be identified through microbiological examination. Antibiotic resistance is a growing problem, and it can make treating urinary tract infections more challenging. If a patient's urine sample shows antibiotic-resistant microorganisms, their healthcare provider may need to prescribe a different antibiotic or a combination of antibiotics to effectively treat the infection.
- Presence of unusual microorganisms: In some cases, microbiological examination may reveal the presence of unusual microorganisms that are not commonly associated with urinary tract infections. These microorganisms may require additional testing to identify and determine the appropriate treatment.
Overall, abnormal findings on a microbiological examination of urine can indicate the presence of a urinary tract infection or other underlying health conditions. If you are experiencing symptoms such as frequent urination, painful urination, or blood in urine, you should contact your healthcare provider for evaluation and treatment.
