Why Rapid STI Testing Matters 

Traditional STI testing often requires days for results to return, causing unnecessary stress and delays in treatment. Rapid testing changes that. By providing same-day or next-day results, you can: 

• Reduce anxiety by getting answersimmediately
• Begin treatment sooner, improving outcomes and reducing transmission risk
• Protect partners through early detection and intervention
• Encourage regular screening due to the convenience and speed of results

Whether you’re testing after a potential exposure, starting a new relationship, or checking as part of routine care, rapid testing makes staying healthy easier than ever. 

1. Rapid HIV Testing – 3rd and 4th Generation Options 

At Hisential, we offer both third-generation and fourth-generation rapid HIV tests, tailored to your situation and testing window. 

Third-Generation Rapid HIV Test 

This test detects HIV antibodies (produced by the body in response to infection). 

• Window period: around 3 to 12 weeks after exposure
• Result time: within 20 minutes
• Purpose: useful for patients testing later after exposure, or for routine screening

Fourth-Generation Rapid HIV Test 

This advanced test detects both HIV antibodies and p24 antigen, a viral protein that appears earlier in infection. 

• Window period: around 2 to 6 weeks after exposure
• Result time: within 20 minutes
• Purpose: ideal for recent exposures where early detection is critical

Both tests are highly accurate when performed after the appropriate window period, and reactive (positive) results are always confirmed by a laboratory-based test. 

2. Rapid Syphilis Testing

Syphilis is caused by Treponema pallidum, a bacterium that can remain silent for years while still causing long-term harm if untreated. 

Hisential’s rapid syphilis test detects antibodies to the syphilis bacterium using a finger-prick blood sample. 

• Window period:typically3 to 6 weeks after exposure 
• Result time: within 15–20 minutes
• Purpose: suitable for early detection and follow-up testing after treatment

Rapid syphilis testing helps ensure that infections are caught as early as possible as symptoms of syphilis may not be obvious. 

3. Rapid PCR Testing for Gonorrhoea and Chlamydia

For gonorrhoea (Neisseria gonorrhoeae) and chlamydia (Chlamydia trachomatis), Hisential uses rapid molecular testing (PCR) — the same technology used in advanced hospital and reference laboratories. 

Unlike conventional cultures that can take days, our rapid PCR test detects the DNA of the bacteria directly, giving results in a few hours. 

• Window period: about 7 to 14 days after exposure
• Result time: within the same day
• Sample types: urine, throat swab, or rectal swab (depending on exposure site)

Why PCR Matters: The Science Behind Sensitivity 

PCR, or polymerase chain reaction, amplifies bacterial genetic material so that even minute amounts of DNA can be detected. The lower the test’s Limit of Detection (LOD), the more sensitive it is. 

Our system’s LOD is among the lowest in the industry — typically around 1 to 10 colonies per millilitre for gonorrhoea and around 100 copies per millilitre for chlamydia. 

This means the machine can identify infection even when bacterial levels are extremely low, ensuring early and accurate diagnosis especially when there may not be any symptoms. 

Why a Low Limit of Detection (LOD) Is Important 

The Limit of Detection defines the smallest amount of genetic material a test can reliably detect. In STI testing, a low LOD means: 

1. Earlier detection: infections are caught at the very start, before bacterial counts rise
2. Higher accuracy: fewer false negatives and missed infections
3. Better reliability across sample types: including urine, vaginal, throat, and rectal swabs

This precision is especially critical for asymptomatic infections — which make up over 70% of chlamydia and gonorrhoea cases. 

Hisential’s PCR system provides laboratory-grade accuracy with clinic-level convenience, making it one of the most advanced rapid STI testing options available in Singapore. 

When Should You Get Tested? 

You should consider STI testing if: 

• You’vehad unprotected sex or a condom break
• You’restarting a new relationshipor have multiple sexual partners 
• You have symptoms such as burning, discharge, or sores
• You want routine peace of mind

If exposure was recent, your doctor will guide you on the ideal timing to test based on the infection type and window period. 

Sometimes, a follow-up test is recommended after several weeks to ensure complete accuracy. 

Who is a Candidate at Hisential Singapore? 

We consider injectable therapies for weight management in patients who: 

• Have a BMI in the overweight or obese range (e.g., ≥27.5 kg/m² for Asians) and one or more weight-related health risks (hypertension, sleep apnoea, diabetes, dyslipidaemia); or 

• Have tried lifestyle change alone for a defined period (e.g., 6-12 months) without sufficient weight loss; and 

• Are motivated to engage with the lifestyle programme (nutrition, activity, follow-up) and understand the commitment involved. 

We do not recommend injectables alone without lifestyle change; nor are they appropriate for everyone (contraindications include certain thyroid, pancreatic or gastrointestinal conditions, pregnancy, or uncontrolled psychiatric illness). Our medical team assesses suitability on a case-by-case basis.
