Biostrep a procedure
  1. Just before testing, add 4 drops of Reagent A (yellow) and 4 drops of Reagent B to the extraction tube. Mix solution by shaking the tube gently. (The solution should turn pink.)
  2. Immediately put the swab into the tube.
  3. Rotate the swab vigorously in the extraction solution to extract specimen thoroughly.
  4. Let stand for 1–2 minutes.
  5. Squeeze out as much liquid as possible from the swab by pressing the swab firmly against the side of the tube with two fingers.
  6. Discard the swab.
  7. Take out the BioStrep A® test strip from the sealed pouch.
  8. Insert the BioStrep A® test strip into the tube of extracted solution and allow the migration to begin.
  9. Read the result in 5 minutes, after a distinct color line has formed in the reading window, but no later than 10 minutes after the test strip has been dipped in the extracted solution.
