Indeterminate on either IGRA implies an immune response on the positive control that is too low to call valid. But note that any positive response would override the low control and would be reported out as positive. That means the vast majority of these indeterminates are negative for TB, but there is concern regarding the patient’s immune system function, and referral to their primary with this information is important.

For an active employee: after the first indeterminate (TSPOT), we redraw in 10 weeks.
We do not change testing type.
If indeterminate the second time we go ahead and them for eval.
98% of the time we get a valid result on the second test.

What protocol do you follow after obtaining two indeterminate results from same individual with two different samples?
