Here some of the terms we use at Awanui Labs Wellington to describe our services and processes.<\/p>\n\n\n\n
Reference intervals compare a patient\u2019s results with the reference range for that test. The \u2018reference interval\u2019 used to be referred to as the \u2018normal range\u2019. Ranges quoted by laboratories represent the values found in 95 per cent of people in the chosen \u2018reference interval\u2019. This gives the best approximation of values to be expected in healthy subjects but there will always be some overlap with values found in subjects with disease. The bigger the deviation of a result from an upper or lower limit of a reference interval, the more likely it is a true abnormal result. <\/p>\n\n\n\n
Uncertainty of measurement describes the windows above and below a measurement result. It defines the range of values in which the true value is estimated to lie. The uncertainty of measurement is\u00a0calculated for every test we report – where it is possible and relevant to do so.\u00a0 It is not presented to requesting practitioners on the report form but it can be provided if requested.<\/p>\n\n\n\n
