SARS COV-2 (Covid-19) Antibody, Qualitative
What is SARS COV-2 (Covid-19) Antibody Test
The COVID-19 test is one of the most important diagnostic tools developed during the pandemic. It helps identify active infection caused by SARS-CoV-2, the virus responsible for COVID-19. The most widely used and trusted method is the RT-PCR test (Reverse Transcriptase Polymerase Chain Reaction test). This molecular test is considered the gold standard because of its high accuracy in detecting even small amounts of the virus.
A COVID-19 test or RT-PCR test is recommended if you have symptoms, have been exposed to a confirmed case, or are planning international travel. Accurate testing ensures early diagnosis, timely treatment, and reduced transmission. At Lupin Diagnostics, patients can easily book COVID-19 test online or book RT-PCR test online from the comfort of their home. Our team ensures transparent reporting and affordable COVID-19 test price and RT-PCR test price.
Why is the COVID-19 Test Important?
Getting a COVID-19 test or RT-PCR test is vital for:
- Early detection – Identifies infection before complications worsen.
- Prevention of spread – Helps isolate positive cases to protect others.
- Travel clearance – Most countries and airlines require an RT-PCR test result.
- Return to work or school – Many employers and institutions mandate a negative COVID-19 test.
- Management of at-risk patients – Elderly individuals and those with diabetes, hypertension, or respiratory illnesses require regular monitoring.
When you book COVID-19 test online or book RT-PCR test online with Lupin Diagnostics, you receive accurate reports at a transparent COVID-19 test price and RT-PCR test price, making testing accessible to everyone.

Interpretation of results
|
Parameters |
Interpretation |
|
Positive |
Indicates previous infection with SARS COV-2 virus; Covid-19 antibodies are present in the blood |
|
Negative |
Shows absence of Covid-19 antibodies; no previous history of infection |
Deviations from the normal result indicate:
- A positive result could also mean antibodies are present in the body after taking the Covid-19 vaccine.
- A false-positive result indicates a positive test result, even though antibodies against the Covid-19 virus are not present in the body. This may be due to the timing of the test, i.e., too early or too late in the infectious stage of the virus.
- A false-negative result indicates that even though antibodies are present in the body against the Covid-19 virus, they go undetected. This may happen if the test was conducted too soon after the infection to detect antibodies.
COVID-19 Test: RT-PCR Test vs Rapid Antigen Test
While the RT-PCR test is the gold standard for diagnosing COVID-19, rapid antigen tests are also available. Both types of COVID-19 tests have their uses, but they differ in accuracy, turnaround time, and purpose.
|
Feature |
RT-PCR Test (Molecular COVID-19 Test) |
Rapid Antigen Test (COVID-19 Test) |
|
Accuracy |
Highest accuracy; considered the gold standard for COVID-19 detection. Detects viral RNA. |
Moderate accuracy; detects viral proteins. May miss early or low viral load infections. |
|
Turnaround Time |
6–24 hours depending on lab processing. |
15–30 minutes, results available quickly. |
|
Sample Collection |
Nasopharyngeal or throat swab, sometimes saliva. |
Nasal or throat swab. |
|
Best Use |
Confirming active infection, travel clearance, return-to-work or hospital admission. |
Quick screening in high-risk areas, workplaces, or large gatherings. |
|
Reliability |
Most reliable and internationally accepted. |
Less reliable; false negatives are more common. |
|
Availability |
Can easily book RT-PCR test online with Lupin Diagnostics at an affordable RT-PCR test price. |
Available in clinics/pharmacies but not always accepted for travel. |
|
Cost |
The RT-PCR test price is slightly higher but provides trusted results. |
Lower cost compared to RT-PCR test. |

Interpretation of COVID-19 Test / RT-PCR Test Results
The results of a COVID-19 test or RT-PCR test are straightforward but extremely important for diagnosis and decision-making.
- Negative COVID-19 Test Result
A negative result means that SARS-CoV-2 (the virus causing COVID-19) was not detected in your sample. However, if you have symptoms or a recent exposure, your doctor may recommend repeating the COVID-19 RT-PCR test after a few days. - Positive COVID-19 Test Result
A positive result confirms active infection. This means the virus’s genetic material was detected through the RT-PCR test. A positive result requires immediate precautions, isolation, and medical consultation. - Inconclusive COVID-19 Test Result
Sometimes, the COVID-19 test may show inconclusive results, especially if the viral load is very low. In such cases, your healthcare provider may recommend a repeat RT-PCR test.
When you book COVID-19 test online or book RT-PCR test online with Lupin Diagnostics, you not only receive accurate results but also transparent updates on the COVID-19 test price and RT-PCR test price.
What to Do if Your COVID-19 Test is Positive
If your COVID-19 RT-PCR test comes back positive:
- Isolate Immediately
Stay at home, isolate yourself from family members, and avoid physical contact to prevent spreading the infection. - Consult Your Doctor
Share your COVID-19 test or RT-PCR test report with your healthcare provider. They will guide you on home isolation, medications, or hospitalization if necessary. - Monitor Symptoms
Keep a close check on fever, cough, oxygen levels, and breathing difficulties. If symptoms worsen, seek emergency care immediately. - Follow Guidelines
Follow local health authority or ICMR guidelines regarding isolation duration, medications, and when to repeat the COVID-19 test. - Retest if Required
In many cases, a repeat RT-PCR test may be recommended after recovery to confirm that the infection has cleared. You can conveniently book RT-PCR test online with Lupin Diagnostics at an affordable RT-PCR test price. - Protect Others
Inform people you had close contact with in the last few days so they can also take a COVID-19 test. They can easily book COVID-19 test online or book RT-PCR test online.
