When performing a Rapid Group A Streptococcus test, after swabbing the patient’s throat, the medical assistant correctly followed the test kit instructions and has waited the recommended time. A single line has appeared on the control (C) region of the test strip, but no line has appeared on the test (T) region. What is the BEST interpretation of this result?
The absence of a line on the test (T) region suggests a negative result for Group A Streptococcus.
A single line on the control (C) region with no line on the test (T) region necessitates immediate antibiotic treatment for the patient.
A line on test (T) region but not on the control (C) region implies a positive result for Group A Streptococcus antigens.
The control region (C) did not show a line, indicating an invalid test that should be repeated.
