Also known as: Swab C/S, Swab CS, Swab Culture and Sensitivity, Throat Swab Culture, Ear Swab Culture, Eye Swab Culture, Wound Swab Culture, High Vaginal Swab, HVS Culture
What is the Swab Culture Test?
A Swab Culture & Sensitivity test uses a sterile cotton-tipped stick to collect germs from a part of the body that is hard to sample any other way, such as the throat, ear, eye, vagina or a shallow wound. Staff take the swab at the centre and send it for culture in a suitable container. Any germ that grows is identified and tested against antibiotics. Each part of the body has its own normal germs, so the report is always read according to where the swab came from.
The purpose changes with the site. A throat swab looks mainly for group A streptococcus in a painful sore throat, which matters because untreated strep throat can lead to rheumatic fever. An ear swab helps with a discharging ear, a high vaginal swab helps with unusual discharge, and a wound swab helps with a sore that is not healing. Most sore throats are viral, so a negative swab can help avoid needless antibiotics. For a collection of thick pus the Pus Culture test is a better fit, and a Gram Stain gives a faster first look.
What it measures: Bacteria or yeast growing from a swab of a named body site, with their antibiotic sensitivity.

How to prepare for the Swab Culture Test
- 1Trained staff take the swab at the centre, so home collection is not available for this test.
- 2Unless a doctor has told you to start them, hold off on antibiotics of any kind until the swab has been taken.
- 3For a throat swab, skip mouthwash and try not to eat or drink for about an hour beforehand.
- 4For a vaginal swab, avoid douching and non-prescribed creams for 24 hours, and tell the staff if you are pregnant or having your period. Ask your doctor about any prescribed pessary.
- 5Tell the staff exactly where the problem is and how long you have had it.
Swab Culture Test normal range
| Parameter | Typical reference range |
|---|---|
| Expected result | No disease-causing germ grown, or only the normal flora of that site |
| Germ grown from the site | Germ named, such as Streptococcus pyogenes in the throat or Pseudomonas aeruginosa in the ear, with sensitivity results |
| Normal flora | Germs that usually live at that site and do not generally need treatment |
What counts as normal depends on the site, which is why the report names where the swab was taken. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A throat swab showing only normal flora makes strep throat less likely, and most such sore throats are viral.
- If a germ grows, your doctor should choose the treatment from the culture report. Depending on the site, this may be drops or a cream and not tablets.
- Yeast such as Candida in the mouth or vagina may need an antifungal medicine, since antibiotics will not treat it.
- A negative swab can follow earlier antibiotics, and it does not detect viruses or some sexually transmitted infections, which need other tests.
- A severe sore throat with drooling, trouble swallowing or trouble breathing needs emergency care.
Swab Culture Test – FAQs
What is the price of the Swab Culture Test?
The Swab Culture & Sensitivity Test costs ₹700 at Live Line Health Care, at all 45 centres.
What is a throat swab culture used for?
It mainly checks for group A streptococcus, a bacterium that causes strep throat and can lead to rheumatic fever if it is not treated. It helps your doctor decide whether antibiotics are needed, since most sore throats are caused by viruses.
Which body sites can be tested with a swab culture?
Common sites include the throat, nose, ear, eye, vagina, cervix, urethra and shallow wounds or skin sores. Your doctor’s request should mention the site. The sample is taken at the centre, and some sites may need a gynaecologist or specialist to collect.
Does a throat swab culture test for viruses?
No. This culture grows bacteria and yeast only, so it will not show flu, COVID-19 or the common cold. Those need separate tests. A report with no disease-causing bacteria simply means a bacterial cause was not found.
Does growth on a vaginal swab always mean infection?
No. The vagina normally holds many bacteria, and some germs, such as Candida or group B streptococcus, can be present without causing illness. Your doctor considers your symptoms and whether you are pregnant before suggesting any treatment.
How is a swab culture different from a Gram stain?
A Gram stain is a same-day microscope look at the sample, showing the broad type of bacteria. A swab culture takes 2 to 3 days but names the germ and tests antibiotics. Doctors often order both when an infection needs a quick first clue.
Should I stop my ear or eye drops before a swab?
Do not stop prescribed drops on your own. Ask your doctor first, as they may want the swab taken before the next dose or a short gap between them. Tell the staff the name of the drops and when you last used them.
Where can I get the Swab Culture Test done?
At any of our 45 Live Line Health Care centres in 40 cities across Andhra Pradesh and Telangana, including Hyderabad, Visakhapatnam, Warangal, Kakinada and Nellore. This test is done at a centre, not at home.
