Quick answer

Hepatitis C testing starts with the antibody test: positive means past or current exposure, but 15-25% clear the virus naturally. Only an HCV RNA test confirms active infection. Modern 8-12 week tablet courses cure over 95% of patients. One-time screening is recommended for all adults aged 18-79.

Hepatitis C testing sequence

Test	Purpose	What positive means
HCV antibody (anti-HCV)	Initial screening test	Past or current HCV infection (antibodies persist lifelong)
HCV RNA (viral load)	Confirms active infection	Virus is present: active infection requiring treatment
HCV genotype	Type of virus (1–6)	Guides choice and duration of antiviral treatment
LFT + liver fibrosis assessment	Assess liver damage	Cirrhosis affects treatment decisions

Key points

A positive HCV antibody test means exposure at some point; about 15-25% of people clear the virus naturally, so antibody alone does not prove active infection.
Only an HCV RNA test confirms current infection; every antibody-positive patient needs one.
Modern direct-acting antivirals cure over 95% of patients with 8-12 weeks of once-daily tablets.
Cure is confirmed by sustained virological response: undetectable HCV RNA 12 weeks after finishing treatment.
Genotype guides treatment choice and duration, though it matters less with modern pan-genotypic drugs.
One-time screening is recommended for all adults aged 18-79, plus anyone who has injected drugs, received transfusions before 1992, or has unexplained raised liver enzymes.

Understanding the antibody vs RNA test

Why both tests are needed

A positive HCV antibody test means you have been exposed to hepatitis C at some point. However, about 15–25% of people clear the virus naturally after acute infection.² They have a positive antibody but negative RNA. Only an HCV RNA test can confirm current (active) infection. All anti-HCV positive patients need an HCV RNA test. If RNA is positive, they have chronic hepatitis C and are candidates for curative antiviral treatment with direct-acting antivirals (DAAs).

Hepatitis C treatment: cure is possible

Modern direct-acting antiviral (DAA) medications such as sofosbuvir/velpatasvir (Epclusa) or glecaprevir/pibrentasvir (Mavyret) cure hepatitis C in over 95% of patients with just 8–12 weeks of once-daily tablets. Treatment is recommended for virtually all patients with chronic HCV. After treatment, a sustained virological response (SVR), undetectable HCV RNA 12 weeks after finishing treatment, means the virus is cured.

Who should be tested for hepatitis C?

All adults aged 18–79 (one-time universal screening recommended in the USA)
Anyone who has ever injected drugs
Recipients of blood transfusions before 1992
People with HIV
People with unexplained raised liver enzymes

Hepatitis C myths vs facts

Hepatitis C is curable, silent, and widely misunderstood. Here is what the evidence actually says:

MYTH A positive hepatitis C antibody means you have it now.

Fact: The antibody stays positive for life even after cure — only HCV RNA (PCR) shows current infection. Antibody positive plus RNA negative usually means cleared infection, not active disease.

MYTH Hepatitis C can't be cured.

Fact: It can — modern direct-acting antivirals cure the large majority in 8–12 weeks with few side effects. ‘Incurable’ is decades out of date; the challenge now is finding the undiagnosed.

MYTH You'd know if you had hepatitis C.

Fact: Most infections are silent for years — fatigue at most — while liver damage accrues quietly. That silence is why risk-based screening (transfusions before screening era, injecting drug use, high-risk exposures) matters.

MYTH There's a hepatitis C vaccine.

Fact: There isn't — unlike hepatitis A and B. Prevention is exposure prevention: safe blood, sterile needles, safe procedures. Don't wait for a vaccine that doesn't exist.

MYTH A negative antibody test after exposure is final.

Fact: Antibodies take weeks to appear — the window period applies. Recent high-risk exposure with a negative antibody needs RNA testing or repeat testing later, per medical advice.

Antibody positive, RNA positive	Current infection — genotype and liver staging follow; curative treatment is available.	promptly; treatment cures most people and stops liver damage.
Antibody positive, RNA negative	Usually cleared infection (spontaneously or treated) — confirm history, no treatment needed.	you're unsure whether you were ever treated.
Antibody negative, recent exposure	Window period may apply — RNA testing or repeat testing per medical advice.	the exposure was high-risk or within the last few months.
At risk, never tested	Old transfusions, injecting drug use, unsterile procedures — screening is a single blood test.	any of these apply; the infection is silent and curable.

Hepatitis C test price in India

In India, the anti-HCV antibody test typically costs &rupee;800–&rupee;1,500, while the confirmatory HCV RNA PCR costs more — usually a few thousand rupees, varying by city and lab. Genotype 3 is the most common in South Asia. Screening is available at most diagnostic chains. Where possible, choose a NABL-accredited lab, and remember the interpretation on your report — antibody versus RNA — is what counts.

Frequently Asked Questions

What's the difference between the antibody and PCR test?

The antibody test shows whether you've ever been exposed to hepatitis C, while the PCR (RNA) test detects the virus itself: confirming a current, active infection.

Is hepatitis C curable?

Yes. Modern direct-acting antiviral tablets cure the great majority of cases within 8–12 weeks, which is why testing and diagnosis are so important.

Can you have hepatitis C without symptoms?

Very often, yes: many people have no symptoms for years while the virus quietly affects the liver, so testing based on risk factors is the main way it's detected.

My antibody is positive but RNA is negative. Am I cured?

It means you do not have active infection — either you cleared the virus naturally or a past infection was treated. The antibody stays positive for life, so RNA remains the test that matters for monitoring. Confirm the interpretation and any follow-up with your doctor.

Can hepatitis C come back after treatment?

Cure (SVR) means that infection is gone, but it does not protect against a new infection — reinfection is possible with fresh blood exposure. Ongoing risk factors mean ongoing caution; discuss any continued risk with your doctor.

Should my family members be tested?

Household transmission of hepatitis C is rare except through blood exposure, so universal family testing is not usually needed. People with shared risk factors (such as past injecting drug use) should be tested. Your doctor can advise who in your situation should be screened.

Is there a vaccine for hepatitis C?

No — unlike hepatitis A and B, there is no vaccine for hepatitis C. Prevention means avoiding blood-to-blood exposure: not sharing needles, razors or toothbrushes, and ensuring safe medical and tattooing practices.

How much does the Hepatitis C test cost in India?

There is no single fixed price — it varies by city, lab, and whether the test is ordered alone or as part of a panel. NABL-accredited labs usually publish their rates online, so it is worth comparing a couple near you. Whatever you pay, the reference range printed on your own report is what counts — discuss the result with your doctor.

Pharmacist's practical notes

The antibody/RNA distinction is the whole test: antibody says “ever exposed,” RNA says “infected now.” Treating an antibody-positive, RNA-negative person — or alarming them — is a real and avoidable error. Always confirm which test your report shows before reacting.

Modern treatment cures most infections in weeks, which reframes every positive RNA as the start of a short curative course rather than a chronic sentence — but the medicines interact with several common drugs, so a pharmacist's interaction check before starting is worthwhile. Never start or stop hepatitis C medicines without specialist supervision.

In India

Where possible, choose a NABL-accredited lab. Screening is available at most diagnostic chains — the undiagnosed are the real reservoir.

HCV antibody versus HCV RNA, why both matter

Hepatitis C testing requires two different types of test at different stages:

Anti-HCV antibody (HCV Ab): Detects the immune system's antibodies against the hepatitis C virus. Becomes detectable 8–12 weeks after exposure. A positive result confirms the person has been exposed to HCV, but does not distinguish between active infection, cleared infection, or successfully treated infection. Antibodies persist for life, even after the virus has been eliminated. Sensitivity is approximately 99% after the window period.
HCV RNA (viral load / PCR): Detects actual virus RNA in the blood. This is the definitive test for active infection. A positive HCV RNA with a positive antibody = current active infection requiring treatment. A negative HCV RNA with a positive antibody = past infection that has been cleared or treated. HCV RNA is also used to monitor treatment response: it should fall to undetectable within 4 weeks of starting antiviral therapy.

Testing sequence: screen with antibody → if positive, confirm with HCV RNA. Do not begin antiviral treatment on the basis of antibody alone, always confirm with RNA.

The HCV genotypes and why they matter less now

There are six major hepatitis C genotypes (1–6), with regional variation: genotype 1 accounts for 70% of UK and US infections; genotype 3 is most common in South Asia. Historically, genotype determined treatment regimen and duration because older interferon-based therapies had different response rates by genotype. The modern pan-genotypic direct-acting antivirals (DAAs), sofosbuvir/velpatasvir (Epclusa), glecaprevir/pibrentasvir (Maviret), achieve 97–99% sustained virological response (SVR, effectively cure) regardless of genotype in most patients. Genotyping is still used in complex cases (prior treatment failure, decompensated cirrhosis) but is no longer required before starting first-line therapy in treatment-naive patients without cirrhosis.

Who needs testing, identifying at-risk populations

HCV is primarily transmitted through blood-to-blood contact.³ High-risk groups where one-time or periodic testing is recommended:

Current or past injecting drug users (IDUs), the primary transmission route in the UK; estimated 50% of IDUs are HCV-positive
Anyone who received blood products or organs before 1992 (when HCV testing of blood supplies began)
Men who have sex with men (MSM), particularly those with HIV or multiple partners
Prisoners (high prevalence in prison populations)
People born or raised in high-prevalence countries (Egypt, Pakistan, Central Asia)
Healthcare workers with needlestick injuries from HCV-positive patients

NICE (2020) recommends offering HCV testing opportunistically in primary care and drug services to all individuals from these groups. Universal opt-out testing in emergency departments and inpatient settings is expanding in the UK as part of the national HCV elimination strategy.
