Indication for Testing

  •  To detect infection after contact with COV-2 infected persons
  • At or before onset of symptoms in addition to PCR test.
  • As a precaution before meeting third party
  • If no PCR test is accessible.
  • As a precaution in case of uncertainty if infection took place.
  • As a follow up after being PCR positive tested, to monitor the status if potentially still infective.

Clinial sensitivity = 201/209=96.17% (95%CI*92.51% to 98.17%)
Clinial sensitivity = 450/450=99.9% (95%CI*98.48% to 100%)
Accuracy: (201+450)/(201+0+8+450) *100%=98.79% (95%CI*97.58% to 99.43%)

Specimen Collection

  • Do not touch your tongue, cheeks, or teeth
    with the swab.
  • Insert the sterile swab through the mouth opening of the patient to the back of the throat.
  • Dab the surface of the back of the throat.
  • Pull the sterile swab out of the oral cavity.
  • For the exact application, please read the package insert


Quick Guide Nasopharyngeal Swab

  • Let blow the nose
  • Tilt head slightly back and support it with the non-dominant hand
  • Insert the swab almost horizontally along the nasal septum deep into the nose up to the pharynx wall
  • Gently rotate the swab for 5–10 seconds to detach epithelial cells.
  • For the exact application, please read the package insert

Test Procedure


Add 300ul (1 phial) extraction buffer (approximately 10 drops) into the reagent tube.


Add the Naso-/oropharyngeal swab to the tube with extraction buffer.


Vigorously rotate and twist the swab against the side of the tube at least 10 times.


Squeeze the sides of the tube to obtain as much as liquid as possible. Dispose the swab properly.


Apply the cap to the tube with specimen, an hold the tube verticaly, add 3 drops (about 80 µl) of the specimen without air bubbles into the sample well.

Result Interpretation


A pink colored band appears only at the control region (C), indicating a negative result for COVID-19 Infections.


A clear pink control band (C) and a detectable test band (T) appears, indicating a positive result for COVID-19 infections.


No visible band appears at the control region. Repeat with a new test kit. If the test still fails, please contact the distributor with the lot number.
