Haemophilus ducreyi BY PCR

The Haemophilus ducreyi BY PCR test is a molecular diagnostic assay that detects Haemophilus ducreyi DNA from clinical swab samples collected at home and processed in accredited Dubai laboratories. By amplifying specific bacterial genetic targets, PCR provides highly sensitive and specific detection to confirm or exclude chancroid as the cause of genital or other skin ulcers. This test is important for prompt, targeted treatment, contact tracing and reducing transmission of sexually transmitted infections in the community.

• Haemophilus ducreyi DNA (Qualitative PCR)
• Internal control (sample integrity)
• Cycle threshold (Ct) value — if reported

• Presence of painful genital or perianal ulcers or sores
• Non-healing or rapidly progressing skin ulcers after sexual exposure
• Recent sexual contact with a partner diagnosed with chancroid or an undiagnosed ulcer
• When clinical symptoms persist despite empirical treatment for other causes
• As part of targeted STI investigation in sexual health clinics or contact tracing

• High sensitivity and specificity through molecular (PCR) detection
• Convenient home sample collection with discreet processing
• Testing performed in accredited Dubai laboratories for reliable results
• Faster and more accurate diagnosis compared with culture-based methods
• Supports targeted antibiotic therapy and public health interventions

• Use the provided sterile swab kit to collect lesion/ulcer specimen as instructed
• Avoid applying topical antiseptics, creams, or antibiotics to the lesion for 24 hours before sampling
• No fasting required; follow kit packaging and courier instructions for timely delivery to the Dubai lab
• Adults 18+ may self-collect; minors require parental/guardian consent in line with UAE healthcare regulations
