Chlamydia (PCR)

The Chlamydia PCR test detects the DNA of Chlamydia trachomatis, providing a highly accurate method for diagnosing an active infection. It is considered the gold standard for chlamydia diagnosis due to its sensitivity and specificity.

Gonorrhea (PCR)

The Gonorrhea PCR test detects the DNA of Neisseria gonorrhoeae, the bacterium responsible for gonorrhea. This nucleic acid amplification test provides highly accurate results for diagnosing an active infection.

HIV 1/2 Antibody + p24 Antigen

The HIV Combo test is a fourth-generation test that detects both HIV p24 antigen and HIV antibodies simultaneously. This dual approach enables earlier detection compared to antibody-only tests, typically within two to six weeks after exposure.

Syphilis (VDRL)

The Syphilis RPR (Rapid Plasma Reagin) test is a non-treponemal screening test that detects antibodies produced in response to syphilis infection. The test measures disease activity and can be used to monitor treatment effectiveness through changes in titre levels.

Hepatitis B Surface Antigen

The HBsAg test is a confidential screening for active hepatitis B infection. Our discreet and professional testing service delivers reliable results while respecting your privacy. A positive result requires further evaluation by a healthcare professional and does not necessarily indicate a chronic condition.

Hepatitis C Antibody

Our confidential Hepatitis C Antibody test screens for anti-HCV antibodies with complete discretion and professionalism. Reliable results are delivered in a supportive, non-judgmental setting. A positive result does not confirm active infection and requires further evaluation by a healthcare professional.

Herpes Simplex 1 IgG

The HSV-1 IgG test detects antibodies to herpes simplex virus type 1, which commonly causes oral herpes (cold sores). HSV-1 is very widespread, with a majority of adults carrying the virus, and it can also cause genital herpes through oral-to-genital contact.

Trichomoniasis (PCR)

The Trichomoniasis test detects the Trichomonas vaginalis parasite, which causes trichomoniasis, the most common curable sexually transmitted infection globally. The infection is often asymptomatic, particularly in men, making testing essential for detection.
