[edit] Confusing

The article says this at the top:

Patients who exhibit a negative reaction may be offered BCG vaccination

The problem is the discussion of the test in the next section doesn't say which grades/results are "negative". Could someone make some tweaks? --87.82.9.62 22:02, 23 April 2006 (UTC)

from the article - The reading of the Heaf test is defined by a scale:
Negative - No induration, maybe 6 minute puncture scars
Grade 1 - 4-6 papules (also considered negative)
So, Negative and Grade 1 would be considered "negative" and everything else is "positive". Petersam 18:18, 24 April 2006 (UTC)
