RV PCR Panel B (9 Viruses)
This complementary respiratory panel detects 9 additional viruses that cause respiratory illness, including coronaviruses and bocavirus. It expands coverage beyond the standard respiratory virus panel.

What the RV PCR Panel B (9 Viruses) test tells you
Respiratory Virus Panel B extends molecular respiratory testing to nine viruses that the standard panel does not include. Its best-known targets are the four seasonal human coronaviruses — 229E, OC43, NL63 and HKU1 — which have circulated in people for decades and typically cause ordinary colds, along with human bocavirus and further respiratory viruses not covered by Panel A. These seasonal coronaviruses are entirely distinct from the virus that causes COVID-19, and a detection here says nothing about that infection, which is tested for separately.
This panel is generally used as a second step rather than a first one. When Panel A comes back negative and the illness still looks viral, when someone is severely unwell or has weakened immunity and the cause genuinely needs a name, or when an unusual cluster of respiratory illness needs explaining, extending the search makes sense. The method is the same multiplex polymerase chain reaction on a nasopharyngeal swab: many genetic targets are searched for at once, so a single collection answers a question that would otherwise require several separate tests.
The viruses on this panel mostly cause mild, self-limiting illness in healthy adults, and identifying one rarely changes treatment directly. What it does change is the reasoning around the illness. It can bring a search for a cause to a sensible close, support the decision not to prescribe antibiotics, and matter considerably in infants, older adults and immunocompromised patients, in whom these same viruses can move into the lower airway and cause serious disease. As with any molecular panel, detecting a virus's genetic material does not prove it is causing your symptoms — carriage and post-infection shedding are both real — so the result is read together with how you actually are.
Used when Panel A is negative but a viral respiratory illness is strongly suspected, or for comprehensive respiratory pathogen assessment in immunocompromised patients.
It covers respiratory viruses left out of the standard panel, which is useful when the first panel is negative and the illness still looks viral.
In infants, older adults and immunocompromised people these viruses can reach the lower airway, so naming the cause carries more weight.
Identifying a benign viral cause can bring a prolonged and worrying search for an explanation to a reasonable end.
A confirmed viral cause supports the decision not to prescribe antibiotics for an illness that will not respond to them.
Reasons your doctor may request the RV PCR Panel B (9 Viruses) test
Your doctor may order this test for any of the reasons below. Some are routine checks, others follow specific symptoms or an earlier result.
When the standard panel was negative
A negative standard respiratory virus panel in someone who remains unwell with viral-looking symptoms.
Recurrent wheezing or cough in a child where the pattern of viral triggers is being worked out.
Weakened immunity, infants & older adults
Severe or prolonged respiratory illness in a patient with weakened immunity.
Respiratory infection in an infant or older adult where the cause needs to be established.
Clusters & hospital admission
An unexplained cluster of respiratory illness in a household, nursery or care setting.
Comprehensive respiratory assessment before or during a hospital admission.
No fasting window — pick any slot that suits you, online or on WhatsApp.
A DHA-licensed nurse collects your sample at home or in the office — free home collection.
A physician-reviewed, easy-to-read report lands securely by WhatsApp and email.

RV PCR Panel B (9 Viruses)
A PCR panel for 9 respiratory viruses.
None of the panel targets were detected — a negative result.
One or more targets were detected. Your report lists which one(s); please consult your physician.
This test is reported descriptively rather than on a numeric scale — each finding below explains what your report may say.
This information is for general education only and is not medical advice. Reference ranges can vary by laboratory, age, sex, and individual factors. Always consult your physician or doctor to interpret your results.
What a higher result can point to
- Infection with one of the seasonal human coronaviruses, which usually causes a common cold but can be more troublesome in vulnerable patients.
- Human bocavirus infection, most often seen in young children with cough and wheeze.
- Another respiratory virus covered by this panel but not by the standard one.
- Ongoing shedding from a recent infection that has already settled clinically.
- Detection alongside a virus found on the standard panel, since more than one can be present at a time.
These are possibilities, not diagnoses. A single value outside the reference range is interpreted alongside your symptoms, history and other tests — your doctor decides what it means for you.
What this test cannot tell you
- Detecting a virus's genetic material does not prove it is causing the illness, since healthy people can shed these viruses without symptoms.
- Molecular tests can stay positive for weeks after recovery, so a detection may reflect an infection that has already passed.
- The seasonal coronaviruses on this panel are not the virus that causes COVID-19, which requires its own test.
- A negative result does not exclude respiratory infection, since bacteria and viruses outside both panels are not covered.
Risks of the blood draw
- Mild bruising or brief soreness where the needle went in.
- Occasional lightheadedness, which settles after a few minutes of rest.
- Bleeding or infection at the site, which is rare with sterile single-use equipment.
- 1The panel searches one nasopharyngeal swab for nine respiratory viruses outside the standard panel.
- 2It is usually a second-line test, used when the first panel is negative or the patient is vulnerable.
- 3Seasonal coronaviruses are ordinary cold viruses and are unrelated to COVID-19 testing.
- 4A detection is interpreted with your symptoms, because carriage and post-infection shedding are common.
- 5Most of these viruses cause mild illness in healthy adults and need no specific treatment.
Frequently Asked Questions
Everything you need to know about the RV PCR Panel B (9 Viruses) test. Can't find what you're looking for?
Talk to our team→No. The seasonal coronaviruses covered here have circulated in people for many years and generally cause a common cold. The virus responsible for COVID-19 is a different one and is not detected by this panel; it has its own dedicated test. A positive seasonal coronavirus result says nothing at all about whether you have COVID-19.
The standard panel covers the most frequent respiratory viruses, but it is not exhaustive. If you still look and feel virally unwell after a negative first panel, extending the search to the viruses in this panel can identify the cause. It is particularly worth doing when someone is severely unwell, very young, elderly or immunocompromised.
Often it will not, because most of these viruses have no specific antiviral treatment and the illness resolves on its own. What it does do is provide a clear explanation, support a decision to avoid antibiotics, and help judge risk in patients who are vulnerable to lower airway complications.
Yes. These viruses are shed by people with no symptoms at all, and genetic material can be detected for a while after an infection has resolved. This is why a detection is never read in isolation: your doctor interprets it in the context of how you feel and what the examination shows.
