We do the same, but treat the borderline
like we would as a post exposure, retesting in 10 weeks for annual testing.
Also, it helps to draw two tubes on
the second dray...I can't explain, but that often gives us a result
If it remains borderline, we send them
for evaluation
If the person is a new hire, we have
to retest immediately, draw two tubes.
If we continue to get a borderline result,
they are sent for evaluation, either our board of health TB unit or an
Id physician.
New hires are responsible for the cost,
we assume the cost for the annuals.
They must be cleared before they can
attend new hire orientation.

Yes, had this happen
more than once with T-Spot. Per their website:
What
should I do with a borderline T-SPOT.TB test result?
Borderline results
are clinically interpretable and should be followed. Retesting by collecting
another sample is recommended. In a study of U.S. healthcare workers, 23%
of subjects with a borderline test result retested as positive, suggesting
the borderline category is useful in maintaining test sensitivity. Upon
retesting, if the test result remains borderline, other diagnostic tests
and/or epidemiologic information should be used to help determine the TB
infection status of the patient.1

We use Interferon Gamma
Release Assays ( IGRA) to test for tuberculosis on all new employees. I
have one new employee that I have tested twice (with approx one month in
between testing) and both times the results were borderline. Has
anyone else had this come up and if so what did you do next? This
employee has no symptoms and no high risk activity such as traveling outside
the country or having contact with anyone with known Tb.
