A count of 5000 to 15 000 asbestos bodies (ABs) or more per gram dry lung tissue (/g dry), or an equivalent uncoated fibre burden of 2.0 million or more amphibole fibres (＞ 5µm in length)/g dry, or 5.0 million or more amphibole fibres > 1 µm in length/g dry; this tissue count of ABs is also roughly equivalent to 5–15 ABs/mL of bronchoalveolar lavage (BAL) fluid.
