OMR, Euglena and Leave a Nest developed and verified an antibody test system for the novel coronavirus disease (COVID-19).

Order-made Medical Research Inc. (President: Yasufumi Murakami), Euglena Co., Ltd. (President: Mitsuru Izumo) and Leave a Nest Co., Ltd. (CTO: Joe Inoue) are jointly developing antibody testing systems. Built and verified​.

We confirmed the accuracy of the constructed antibody test system using clinical specimens (hereinafter referred to as “samples”) obtained informed consent from medical institutions.

As a result of the antibody test constructed against those samples that had been tested positive in the PCR test, a positive result was obtained in all of the 75 samples collected 11 days after the onset. This indicates 100% sensitivity in the test.
Similarly, in the antibody test performed on 36 samples that were negatively determined by PCR, all samples were negative. This result shows that the specificity is 100% for both sensitivity under the conditions of the test.※ 1.

Regarding the antibody test system constructed by joint development, the above test results correctly identify the person who has the antibody against the new coronavirus, and the test result of the person who does not have the antibody is falsely determined to be positive. This suggests the possibility of conducting accurate tests that are not performed. This result is an important progress in putting a highly accurate test system to practical use, and in the future we will proceed with research and development aiming to establish a more reliable antibody test system.
*1 The specificity and sensitivity percentages obtained this time show the degree of agreement with the PCR test.
