Diagnosis / Prognosis - Bacterial Culture
Diagnosis / Prognosis - Polymerase Chain Reaction (PCR)

Experimental: ellume·lab Group A Streptococcus Test - ellume·lab Group A Streptococcus Test

Pharyngeal samples from participants will be tested with:

ellume.lab Group A Streptococcus Test; Polymerase Chain Reaction (PCR) and bacterial culture.


Diagnosis / Prognosis: ellume·lab Group A Streptococcus Test
ellume.lab Group A Streptococcus Test is a rapid diagnostic test intended to be used as an aid in the diagnosis of Group A Streptococcus in symptomatic participants. The sample type used is a throat swab.

Diagnosis / Prognosis: Bacterial Culture
Pharyngeal swab is collected from participant and this specimen is inoculated into 5% sheep blood agar plates. Beta-haemolytic colonies are isolated, followed by latex agglutination test.

Diagnosis / Prognosis: Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) is a molecular diagnostic technique for the detection and identification of Group A Streptococcus, both for clinical samples and isolates. Polymerase Chain Reaction (PCR) allows template bacterial RNA to be reverse transcribed producing complementary DNA (cDNA) which can then be amplified and detected.
