Introduction
The examination for sexually transmitted diseases generally includes serological testing, pathogen culture and drug sensitivity testing, nucleic acid testing, analysis of secretions, and imaging studies. If any abnormalities are detected, timely medical consultation is recommended. To reduce the risk of infection, it is important to maintain good personal hygiene, avoid contact with potentially contaminated bodily fluids or blood, uphold healthy lifestyle habits, and take care of overall health.
Examinations for sexually transmitted diseases (STDs) generally involve serological testing, pathogen culture and drug sensitivity testing, nucleic acid testing, secretion analysis, and imaging examinations. If abnormalities are detected, timely medical consultation is recommended. Detailed explanations are as follows:
1. Serological Testing: This method detects antibodies related to STDs using blood samples. For example, screening for syphilis and AIDS primarily relies on blood testing. This method can determine whether specific pathogen antibodies exist in the patient's body, thus indicating whether an STD infection is present.
2. Pathogen Culture and Drug Sensitivity Testing: This method involves collecting urethral or cervical secretions for pathogen culture and drug sensitivity testing. By culturing the pathogen, the infection type can be identified, and drug sensitivity testing can reveal which medications are effective against the pathogen, providing a basis for treatment.
3. Nucleic Acid Testing: This method uses molecular biology techniques to detect the DNA or RNA of pathogens. It enables rapid and accurate diagnosis of STDs, such as detecting genital herpes virus and human papillomavirus.
4. Secretion Analysis: This primarily examines genital tract secretions such as cervical mucus, semen, and urine. By analyzing the color, odor, pH value, and microscopic examination of the secretions, pathogens such as gonococci, trichomonads, and fungi can be identified.
5. Imaging Examinations: These mainly include ultrasound (B-scan), computed tomography (CT), and magnetic resonance imaging (MRI). These tests allow visualization of the reproductive organs and surrounding tissues, helping diagnose complications caused by STDs, such as pelvic inflammatory disease and prostatitis.
To reduce the risk of infection, it is important to maintain good personal hygiene, avoid contact with potentially contaminated bodily fluids or blood, and adopt healthy lifestyle habits to safeguard overall health.
