From $1860.00*





HIV Pre exposure Prophylaxis (HIV PrEP) is taken to reduce the chance of HIV infection

HIV Post exposure Prophylaxis (HIV PEP) can reduce the chance of HIV infection within 72 hours after potential HIV exposure

HIV is detectable in the blood in as early as 10 – 11 days post exposure. HIV RNA/DNA Polymerase Chain Reaction (PCR) Test is also used for HIV positive persons to check the HIV viral load.

HIV P24 Antigen will appear in the blood between 14 to 20 days. HIV IgM Antibody starts to become detectable in the blood.
HIV P24 Antigen & IgM Antibody can be detected with 4th Generation tests (aka HIV Combo tests)

The results of this HIV test are available within 20 minutes

* Prices mentioned above are inclusive of 7% GST.

Consultation fees will apply.

Preserving patient confidentiality is our utmost priority. Therefore reports will NOT be snail mailed by post. Results can be communicated via phone or email.

During the private consultation, you can speak to our doctors about your HIV-related concerns. The doctor will then recommend the correct HIV Test or STD test.

Our registered doctors will administer the HIV and STD tests, which are approved by Health Sciences Authority (HSA).

HIV Pre-Exposure Prophylaxis (PrEP)

HIV Pre-Exposure Prophylaxis (PrEP) is a preventive treatment that can reduce the chances of HIV infection when an individual is exposed to HIV. HIV PrEP needs to be taken daily to significantly reduce his/her risk of contracting HIV.

Even while on this medicine, we will still strongly advise the patient to continue practicing safer sex and get regular HIV tests. HIV PrEP does not prevent other STDs.

HIV Post-Exposure Prophylaxis (PEP)

HIV Post-Exposure Prophylaxis (PEP) is a preventive treatment after a person has been potentially exposed to HIV. HIV PEP is effective only within 72 hours after HIV exposure.

Polymerase Chain Reaction (PCR) HIV RNA/DNA TEST

HIV PCR RNA test is used to detect HIV viral genes at the very early stage of HIV infection before antibodies have developed. HIV PCR RNA test is also used to test for HIV Viral Load (VL) counts for people living with HIV, who are undergoing HIV treatment   (HAART)

HIV P24 Antigen/Antibody Combo Test (4th generation)

Also known as the 4th Generation HIV Test, HIV P24 Antigen/Antibody Combo Test  detects HIV antigen (P24) and/or HIV antibodies. HIV P24 develops during Day 14 to Day 20 after an HIV infection. P24 peaks at about Day 20. IgM Antibodies starts to develop on Day 20 to Day 23.

HIV Window period & HIV Test Accuracy

HIV window period is the time between potential HIV infection and the time an individual can get tested with an accurate result.

When a HIV test is done during the window period, a person may be infected with HIV but the test result will be reflected as negative. This is called a HIV false negative result.

Different HIV tests have different HIV testing window periods, as different HIV tests detect different indicators of HIV during the HIV development cycle.


HIV PEP Period
(Day 0 – 3)

Eclipse Period
(Day 0 – 10)

Acute HIV Infection Day 10

Acute HIV Infection
(Day 14 to 20)

Acute HIV Infection
(Day 20 to 23)

Acute HIV Infection
(Day 28 to 48)

Chronic HIV Infection
(Day 90 & above)

HIV Development Stage

After Potential HIV Exposure

HIV Virus RNA/DNA is detectable in blood

HIV P24 is detectable and peaks at about day 30

IgM Antibodies is detectable

IgG Antibodies is detectable

HIV Antibody

Type of HIV Tests

No HIV test is available

No HIV test is available

HIV RNA/DNA Polymerase Chain Reaction (PCR) Test

HIV Combination P24 Antigen/Antibody Test (HIV Duo Test) Lab test

Rapid Fingerprick Blood HIV-1/2 P24 Antigen/Antibody Combo (HIV Duo Test)

HIV Antibody Test (ELISA)

Rapid Fingerprick Blood HIV-1/2


HIV Post exposure Prophylaxis (HIV PEP) can reduce the chances of HIV infection within 72 hours after potential HIV exposure

HIV RNA PCR test has a low chance of giving a false positive result. If the RNA PCR test gives a report of < 5000 viral copies per ml, it is likely a false positive.

Stages of HIV Infection

HIV Mode of Transmission

HIV survives in certain body fluids such as semen, pre-seminal, vaginal fluids, rectal fluids, breast milk and so on. The HIV infected body fluids must come in contact with mucosa membrane, damages tissues or injected in the bloodstream for transmission to occur.

HIV is most commonly sexually transmitted through unprotected sex with an HIV infected individual.

HIV can be transmitted through:

  • Blood Transfusion
  • Injection Drugs Use
  • Needle Stick Injury
  • Vaginal Sexual Intercourse (Receptive or Insertive)
  • Anal Sexual Intercourse (Receptive or Insertive)
  • Mother to Child
  • Organ Transplant

Risk of HIV Transmission

Different studies show different HIV Transmission Risk.

Below is a summary based on US CDC MMWR, UK guideline for the use of PEP (UK PEP), Alberta guideline for the use of  PEP (Alberta PEP), Australian Society for HIV Medicines (ASHM) and New York State Department of Health AIDS Institute (New York).

As expected there are large discrepancies in the estimated risks. Receptive anal intercourse is invariably the highest risk sex act.

Factors Influencing Transmission Risks

  1. Condoms - There have been many studies on the effectiveness of condoms in reducing HIV risk. Results range from 60% to 90%. The US CDC Condom Report published in 2001 estimated the average protection rate to be 87%. Condom use should therefore be encouraged for all patients.
  2. Treatment as Prevention – People living with HIV on AntiRetroviral Therapy (ART) are about 90% less likely to transmit HIV. This could be due to the decreased viral load.
  3. Circumcision – Circumcision has been found to reduce the risk of contracting HIV by about 60%. This may be due to the removal of the foreskin which is rich in Langerhan Cells.
  4. Other Factors:
Male-to-Female Transmission

Oral Contraceptives

Gonococcal Cervicitis (Gonorrhea infection of the Cervix)

Candida Vaginitis

Genital Ulcers

Bacterial Vaginosis

Herpes simplex virus (HSV) 2

Vitamin A Deficiency

Female-to-Male Transmission

Lack of Circumcision

Genital Ulcer

Sex During Menses

Herpes simplex virus (HSV) 2
