Note: IGRA interferon-gamma release assay.
This table is sorted by consistency of positive postpartum IGRAs. The first nine rows display IGRA responses in women who had all positive postpartum IGRAs. The next 6 rows display IGRA responses in women who fluctuated between positive and negative IGRAs postpartum. The last 3 rows display IGRA responses in women who had all negative postpartum IGRA.
*Maximum of ESAT-6/CPF-10 minus negative control.
^†Blank cells represent visits with indeterminate responses.
^‡Consistent positive IGRAs is defined as all postpartum visits with positive IGRAs, excluding visits with indeterminate responses.
