CPT4 code
Name of the Procedure:
Group A Strep Test Performed (PHAR) Common name(s): Strep Test, Rapid Strep Test, Rapid Antigen Detection Test (RADT)
Summary
A Group A Strep Test is a simple and quick procedure used to detect the presence of Group A Streptococcus bacteria in the throat. This test is often conducted when a sore throat is suspected to be strep throat.
Purpose
The test addresses pharyngitis (sore throat) caused by Group A Streptococcus bacteria. It aims to confirm or rule out a strep infection to direct appropriate treatment, typically antibiotics, and prevent complications like rheumatic fever.
Indications
Symptoms warranting the procedure include:
- Sore throat
- Red and swollen tonsils, sometimes with white patches or streaks of pus
- Swollen, tender lymph nodes in the neck
- Fever
- Headache
- Rash
Patients with these symptoms, especially if there is a known exposure to strep throat, should consider testing.
Preparation
No special preparation is required for a Group A Strep Test. Patients can eat, drink, and take medications as usual before the test.
Procedure Description
- The patient is asked to open their mouth wide.
- A sterile swab is gently rubbed over the back of the throat and tonsils to collect a sample of mucus.
- The sample is then tested using a rapid antigen detection kit or sent to a lab for a throat culture.
- Results from the rapid test are usually available within minutes, while lab results may take a few days.
Tools: Sterile swab, rapid antigen detection kit. Anesthesia: None.
Duration
The procedure typically takes only a few minutes.
Setting
The test can be performed in various settings including:
- Pharmacies
- Doctor's offices
- Urgent care clinics
- Hospitals
Personnel
Usually conducted by a pharmacist, nurse, or doctor.
Risks and Complications
The test is generally safe with minimal risks. Rarely, the swab may cause gagging or discomfort.
Benefits
- Quick and accurate diagnosis of strep throat.
- Prompt treatment to relieve symptoms.
- Prevention of complications from untreated strep throat.
- Benefits can be realized immediately with appropriate treatment.
Recovery
No recovery time is needed. Patients can resume normal activities right after the test. If positive, a course of antibiotics will be prescribed, which typically leads to symptom improvement within a few days.
Alternatives
- Throat Culture: More accurate but takes longer to get results.
- Clinical assessment without a test: May lead to misdiagnosis.
Patient Experience
The patient might feel slight discomfort or a gagging sensation during the swabbing. No pain relief is typically needed, and the discomfort is temporary. Most patients can go through their day normally after the procedure.
