Can I compare the test results for the Modified Lowry and ELISA Inhibition Assay tests?

No. The ELISA Inhibition assay is a method used to test for antigenic latex proteins. The Modified Lowry assay is a method used to test for total water-extractable protein. Because each test method determines a different substance (total vs. antigenic protein) and employs different procedures, the end results cannot and should not be compared.
