Read the full statement (176 words)
The CareSuperb COVID-19/Flu A&B Antigen Combo Home Test is a lateral flow immunochromatographic assay
intended for the qualitative detection and differentiation of influenza A and influenza B nucleoprotein antigens and
SARS-CoV-2 nucleocapsid antigens directly in anterior nasal swab samples from individuals with signs and symptoms of
respiratory tract infection. Symptoms of respiratory infections due to SARS-CoV-2 and influenza can be similar. This test
is for non-prescription home use by individuals aged 14 years or older testing themselves, or adults testing individuals
aged 2 years or older.
All negative results are presumptive and should be confirmed with an FDA-cleared molecular assay when determined to
be appropriate by a healthcare provider. Negative results do not rule out infection with influenza, SARS-CoV-2, or other
pathogens.
Individuals who test negative and experience continued or worsening respiratory symptoms, such as fever, cough, and/or
shortness of breath, should seek follow up care from their healthcare provider.
Positive results do not rule out co-infection with other respiratory pathogens and therefore do not substitute for a visit to a
healthcare provider for appropriate follow-up.
Indications for use as stated in the FDA summary.
