How to take, the dosage
Sample collection and preparation
- The COVID-19 IgG/IgM express test is intended for use only with human whole blood (capillary or venous), serum or plasma samples.
- Only clear, unhemolyzed samples are recommended for use with this test. Serum or plasma should be separated as soon as possible to avoid hemolysis.
- Test immediately after collecting samples. Do not leave samples at room temperature for extended periods of time. Serum samples can be stored at 2-8°C for up to 3 days. For long term storage, serum samples should be stored below -20°C and should not be refrozen once thawed.
- Fresh samples to room temperature before testing. Frozen samples must be completely thawed and thoroughly mixed before testing. Avoid repetitive freezing or thawing of the samples.
- If the samples must be shipped, package them according to all applicable regulations for shipment of etiological agents.
- Icteric, lipemic, hemolyzed, heat treated and contaminated sera can lead to erroneous results.
TESTING PROCEDURE
Bring reagents and biological sample to room temperature before testing.
- Remove the test card from the reagent package and use within 1 hour.
- Place the test card on a clean and flat surface.
Extract a whole blood sample from a vein or finger, or a serum or plasma sample. Using the disposable pipette provided, draw 10 µl of serum/plasma sample (corresponding to the first black fill line on the pipette) or 20 µl of whole blood sample (corresponding to the second black fill line on the pipette) and transfer sample to well A on the test card, then add 2 drops of buffer solution to well B and start timing.
3 Wait for the colored line C to appear, indicating that the test was performed correctly. The results should appear within 5-10 minutes. Do not accept the result after 15 minutes.
Special Instructions
The alcohol wipe and lancet are not included.
QALITY CONTROL
The internal quality control process is included in the test. The colored line that appears in the control area (C) is an internal positive procedural control. It confirms sufficient sample volume and correct methodology.
