False negative tests may be caused by:
miliary TB
sarcoidosis
HIV
lymphoma
very young age (e.g. < 6 months)
Heaf test
The Heaf test was previously used in the UK but has been since been discontinued. It
involved injection of PPD equivalent to 100,000 units per ml to the skin over the flexor
surface of the left forearm. It was then read 3-10 days later.

exacerbations of her asthma and recently required a course of prednisolone. What is the most
appropriate next step in management?
Add a leukotriene receptor antagonist
Add tiotropium
Add salmeterol
Start to take the salbutamol regularly, 2 puffs qds
Switch beclometasone to fluticasone
