*5.2.7 Indirect fluorescent antibody (IFA) test*

This test is quick, with findings available in just a couple of hours in the same illustration of ELISA. However, the interpretation of results is subjective, and it might not differentiate between IgA, and research findings have shown that different manufacturers produce varying levels of antibody responses to the same antigens.

### *5.2.8 Immunochromatographic lateral flow assay*

The test is easy to perform and read, simple, and rapid, with high sensitivity and specificity (> 90%).
