Purpose: This service aims to analyze the urethral discharge sample to detect the presence, quantity, and type of microorganisms present in the urethral tract. It is especially useful for diagnosing sexually transmitted infections (STIs) such as gonorrhea and other bacterial or fungal infections. Common indications: It is performed on people with suspected urethral infection, presenting symptoms such as abnormal discharge, pain when urinating, or any other discomfort related to the urethra. Sampling: A sample of the urethral discharge is collected using a sterile and specific method recommended by the health professional. The sample can be obtained using a sterile swab that is carefully introduced into the urethra to collect the discharge. Gram staining: The collected sample is subjected to the Gram staining technique, a laboratory procedure in which special dyes are applied to differentiate between gram-positive and gram-negative bacteria, as well as other microbial characteristics. Microscopy and analysis: After staining, the stained sample is examined microscopically to observe the morphology, quantity, and type of microorganisms present in the urethral secretion. Interpretation of results: Microscopic observation allows the identification and characterization of the microorganisms present in the urethral secretion, which helps in the diagnosis of possible infections and in determining the appropriate treatment. Follow-up: The results obtained from this analysis are essential for the diagnosis and treatment of urethral infections. If an infection is identified, appropriate treatment may be prescribed, such as antibiotics or other medications, depending on the nature and sensitivity of the microorganisms detected.
