Introduction
Urethral swabs are clinically used to test urethral secretions. The procedure involves inserting a urethral swab into the urethral opening, gently rotating it to collect a sample, and then removing it for bacterial culture. Before undergoing the test, patients should clean the urethral opening with water and keep the area hygienic and dry. It is important that patients avoid urinating for at least two hours prior to the test, as urination may wash away microorganisms in the urethra and lead to inaccurate test results.
Urethral swabs are clinically used to test urethral secretions. The procedure involves inserting a urethral swab into the urethral opening, gently rotating and rubbing it to collect samples for bacterial culture. This examination should be performed at a正规 medical facility. The specific steps are as follows:
1. Before the urethral swab test, the patient should clean the urethral opening with water and keep the area clean and dry.
2. After entering the examination room, the patient lies on the examination table in the lithotomy position.
3. The doctor moistens the urethral swab with normal saline and inserts it 2 to 3 centimeters into the urethra.
4. The swab is rotated evenly inside the urethra to gently rub the urethral mucosa, collecting secretions. Then, the swab is removed and placed into a specimen container for laboratory testing.
It is important that the patient avoids urinating for at least two hours prior to the test, as urination may flush out urethral secretions and lead to inaccurate results.
