Streptococcal screen

What is Streptococcal Screen?

Streptococcal screen is a set of tests used to identify the presence of bacteria known as Streptococcus in individuals. It is used to diagnose conditions like sore throat, impetigo, and other infections.


The doctor typically prepares for the test by taking a throat culture or a swab of the infected area. The sample is sent to the laboratory for analysis, and the results are ready within 24-48 hours.


The test is a simple one and only takes a few minutes. The doctor inserts a swab into the throat or the infected area and collects a sample of cells and fluid. Once the sample is collected, the doctor prepares a sample for analysis in a special agar plate. The doctor then places a drop of the sample onto the test strip and incubates the strip in an incubator for 1-2 days. The results are then analysed and the doctor determines if the Streptococcus is present or not.

Types of Streptococcal Screen

There are two different kinds of Streptococcal screens; the rapid screening test and the throat culture. The rapid screening test is a quick and relatively inexpensive option that can provide results within an hour. The throat culture test takes longer and is more expensive, but is more accurate and provides more detailed information than the rapid test.

Risks Associated with a Streptococcal Screen

The risks associated with a Streptococcal screen are minimal, and the procedure has no risks when conducted correctly. The results of the screening test are usually accurate and reliable.

Why is a Streptococcal Screen Necessary?

A Streptococcal screen is necessary because it can diagnose and treat certain Streptococcus infections quickly and accurately. Because Streptococcal infections can be serious and lead to serious complications if left untreated, it is important to get an accurate streptococcal test as soon as possible.

When is a Streptococcal Screen Needed?

A Streptococcal screen is usually done when a person is experiencing symptoms of a Streptococcus infection, such as a sore throat, rash, fever, or headaches. It can also be done to check for exposure to a Streptococcus infection if a person has been exposed to someone who has a known infection.
