Specifically, you ask for assistance classifying a dried blood sample under the following circumstances: • A dried blood sample on absorbent material when the blood sample on the material comes from a community study on influenza infection where the subjects are not known or presumed to be infected. • A dried blood sample on absorbent material when the blood sample on the material comes from a community study on COVID-19 infection where the subjects are not known or presumed to be infected. • A dried blood sample on absorbent material when the blood sample on the material comes from a subject that is presumed to be infected with influenza. • A dried blood sample on absorbent material when the blood sample on the material comes from a subject that is presumed to be infected with COVID-19. In each circumstance, § 173.134(b)(9) states that dried blood spots placed on absorbent filter paper or other material are not subject to the requirements of the HMR. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, T.
