1. Internal Control: This test contains a built-in control feature, the C line. The C line
develops after adding specimen and sample diluent. If there is no visible C line, review
the whole procedure and repeat the test using a new device.
2. External Control: Good Laboratory Practice recommends using the external controls,
positive and negative, to assure the proper performance of the assay, particularly under
the following circumstances:
a. A new lot of test kit is used.
b. A new shipment of kits is used.
c. The temperature during storage of the kit falls outside of 2-30℃.
d. The temperature of the test area falls outside of 15-30℃.

f. To investigate the cause of repeated invalid results.
INTERPRETATION OF ASSAY RESULT
If only the C line is present, the absence of burgundy color in test
lines (T) indicates that no novel coronavirus is detected. The result is negative or
In addition to the presence of C line, if the T line develops, the test result indicates that
novel coronavirus is detected. The result is novel coronavirus positive or reactive.
Samples with positive results should be confirmed with alternative testing method(s)
and clinical findings before a diagnosis is made.
If no C line develops, the assay is invalid regardless of burgundy color in the
test lines as indicated below. Repeat the assay with a new device.
