Detection Area: TEST ELISA-in house to quantify anti-RBD antibodies.

The RBD domain produced was immobilized (as detailed in the project for therapeutic purposes) and a detection and semi-quantification test for anti-RBD antibodies was developed by means of an ELISA immunoassay. The test was validated using 1,180 sera from a public entity laboratory. The ROC analysis showed that the test has excellent discriminating power, sensitivity, and specificity.
