Arterial blood gas (ABG) testing assesses gas exchange, acid/base status and provides immediate information on electrolytes. ABG analysis helps to diagnose respiratory failure and may reveal acid/base disturbance (and if the body is compensating or not).

Allergic bronchopulmonary aspergillosis (ABPA) is characterised by a hypersensitivity allergic response to the spores of Aspergillus mould. ABPA is the non-invasive form of aspergillosis.

ABPA is most common in people with asthma, CF or bronchiectasis.

The ankle-brachial pressure index (ABPI) is the ratio of the systolic blood pressure at the ankle (highest of the dorsalis pedis and posterior tibial artery pressures) to the systolic blood pressure in the upper arm (brachial artery pressure).

ABPI is measured on the same side of the body (left ankle compared with left upper arm).

Lower blood pressure in the leg than the arm (a low ABPI, less than 1) suggests blocked arteries due to PAD.
