Hepatitis C RNA PCR Testing

A Hepatitis C RNA PCR test requires a small blood sample, usually taken from a vein in your arm.

Unlike an antibody test, which detects past exposure, the PCR test looks for the genetic material (RNA) of the virus to confirm whether you have a current active infection. Results may be available within a few hours, depending on the testing method used.

Preparing for a Hepatitis C RNA PCR test is simple. Stay well hydrated before your appointment, as this can make the blood draw easier.

You do not need to fast and can eat and drink as normal. Wearing clothing with loose sleeves may also make the blood sample easier to collect. If you require a test certificate, bring a valid photo ID such as a passport or driving licence.

A Hepatitis C RNA PCR test can usually detect the virus 1 to 3 weeks after exposure.

Because it detects the virus directly rather than your immune response, it can identify infection much earlier than an antibody test. Depending on when the exposure occurred, repeat testing may sometimes be recommended.

A Hepatitis C RNA PCR test detects the genetic material (RNA) of the virus in your blood.

The test uses a laboratory technique called polymerase chain reaction (PCR) to amplify tiny amounts of viral RNA, making it possible to detect even very low levels of the virus. This makes PCR testing highly sensitive and the preferred method for confirming an active Hepatitis C infection.

Hepatitis C RNA PCR testing is considered the gold standard for diagnosing an active Hepatitis C infection.

It is highly sensitive and specific, with an accuracy of over 99% when performed at the appropriate time after exposure. It can detect the virus before antibodies develop and is also used to monitor the response to treatment.

A Hepatitis C RNA PCR test can usually detect the virus 1 to 3 weeks after a potential exposure, making it the preferred option for early testing.

It is also recommended to confirm an active infection after a reactive Hepatitis C antibody test or to monitor treatment. If you are unsure when to test, your healthcare provider can advise you based on your circumstances.

A physical examination is not usually required for a Hepatitis C RNA PCR test.

The test only requires a blood sample. If you have symptoms or other health concerns, your healthcare provider may recommend an examination as part of a broader assessment.

Yes. There are two main types of Hepatitis C RNA PCR tests:

• Qualitative PCR: Confirms whether the virus is present.
• Quantitative PCR (viral load): Measures the amount of virus in your blood and is commonly used to monitor treatment.

Genotyping may also be performed in selected cases, although it is now less important because many current treatments are effective against all hepatitis C genotypes. Your healthcare provider will recommend the most appropriate test based on your medical history and the reason for testing.

You can receive your test results by either text or email.

The results will be either NOT Detected (i.e. negative) or DETECTED (i.e. positive).

In some cases, the test may come back as invalid or inconclusive which means that it was not possible to gain a conclusive result from the sample given. If this happens, we will request another sample free of charge.

Yes. While waiting for your results, take steps to reduce the risk of passing Hepatitis C to others.

• Do not share items that may come into contact with blood, such as razors, toothbrushes, or nail clippers.
• Keep any cuts or wounds covered with a waterproof dressing.
• Do not share needles or other injecting equipment.
• Avoid donating blood, organs, or semen until your results are confirmed.

Although the risk of sexual transmission is generally low, using condoms until your results are available is recommended.

A positive Hepatitis C RNA (PCR) result means you have a current active Hepatitis C infection.

Before treatment, additional blood tests, including liver function tests, may be recommended to assess your liver health. Where appropriate, your healthcare provider may also assess the degree of liver fibrosis (scarring), for example using a FibroScan® or other non-invasive tests.

Modern direct-acting antiviral (DAA) medications are highly effective and cure most people within 8–12 weeks. Your healthcare provider will discuss your results, explain your treatment options, and arrange any necessary follow-up care.

If your hepatitis C antibody test is reactive (positive) but your HCV RNA (PCR) test is negative, there is no evidence of a current active hepatitis C infection. A positive hepatitis C antibody test usually means you were infected with the virus at some point in the past. This may be because your body cleared the infection naturally or because treatment was successful. Hepatitis C antibodies usually remain detectable for life, even after the virus has been cleared, so the antibody test will often remain positive. If there is concern about a recent exposure or your clinical circumstances change, your clinician will advise whether any further testing is needed.

You are not legally required to tell your partner if you test positive for Hepatitis C. However, current or recent partners may wish to discuss testing with their healthcare provider, particularly if there has been a risk of blood exposure.

While sexual transmission is uncommon, it can occur in some circumstances. Until you have discussed your diagnosis with your healthcare provider, avoid sharing items that may have blood on them and consider using condoms during sex.

Yes. A certificate of your Hepatitis C RNA PCR test results can be provided if required for official purposes.

Please bring a valid photo ID, such as a passport or driving licence, so your certificate can be issued accurately.
