Description

A study has been made of the effect that different methods of breath collection have on the measurement of calcium in vivo by the 40Ca(n,α)37Ar method. The effect of open and rebreathing breath collection methods has been examined by using intravenous injections of 133Xe. This study has indicated that comparison of calcium measurements between individuals and between centres is likely to be accurate only if breath is collected on 'open circuit'. (author)
