The mitogen tube must demonstrate an interferon- value of equal to or greater than 0.5 IU/ml higher than the value of the NIL tube. Binding between the monoclonal antibodies and isoluminol in the conjugate is mediated by a biotin-streptavidin immunocomplex. The COVID-19 pandemic required suspension of NHANES 2019-2020 field operations in March 2020 after data were collected in 18 of the 30 survey locations in the 2019-2020 sample.
