Summary
Polymerase chain reaction (PCR) rapidly diagnosed genitourinary tuberculosis when smears were negative. This molecular test offers high sensitivity for timely diagnosis and treatment initiation.
Area of Science:
- Microbiology
- Infectious Diseases
- Molecular Diagnostics
Background:
- Genitourinary tuberculosis (GUTB) diagnosis can be challenging.
- Traditional diagnostic methods like direct smear examination have limitations in sensitivity.
Observation:
- A patient with suspected GUTB presented with a negative direct smear examination.
- Mycobacterial DNA detection using polymerase chain reaction (PCR) was performed.
Findings:
- PCR established the diagnosis of genitourinary tuberculosis.
- Culture confirmation was achieved 4 weeks after PCR detection.
- PCR demonstrated very high sensitivity and positivity in this case.
Implications:
- PCR may become the preferred method for rapid GUTB diagnosis.
- Early diagnosis via PCR facilitates prompt therapeutic intervention.
- Molecular diagnostics like PCR enhance the management of infectious diseases.
