Diagnostikföretaget Quidel Ortho har mottagit minst 31 klagomål relaterade till ett test som används för att upptäcka halsfluss orsakad av grupp A-streptokocker (GAS).

Företaget bekräftar problemet i ett säkerhetsmeddelande till Läkemedelsverket. Där framgår att andelen falskt positiva resultat tidigare låg kring 10 procent, men nu har ökat till så mycket som 40 procent i vissa berörda partier av testet Quick Vue Dipstick Strep A Test.
