Transference and validation of reference intervals.
Reference intervals are the most widely used decisionmaking tool in laboratory medicine and serve as the basis for many of the interpretations of pathology results. Although laboratories are well versed in method verification and validation to assess if methods are fit-for-purpose, less importance is commonly put on selecting the most appropriate reference interval to determine whether an indiv...

quencer, confirming the high quality of the purified DNA. This is reflected by the high A260/A280 ratio (Table 1) and was confirmed by agarose gel electrophoresis. The silica matrix offers a degree of flexibility in optimizing the mass of matrix required to bind sufficient DNA for the application, whereas the silica discs provide a laminar format perhaps more suitable for molecular diagnostic d...
متن کاملMethod-specific reference intervals for serum anion gap and osmolality.
To the Editor: We wish to comment on reference intervals for the serum anion gap and osmolality. The serum anion gap, which is most commonly defined as AG 5 Na-Cl-TCO2, traditionally has had a reference interval of 8 –16 mmol/L with a mean value (i.e., mean of values used to determine its reference interval) of 12 mmol/L (1, 2). In a recent report (3), the stated reference interval for the anio...
متن کاملIndirect reference intervals estimated from hospitalized population for thyrotropin and free thyroxine.
AIM To establish indirect reference intervals from patient results obtained during routine laboratory work as an alternative to laborious and expensive producing of their own reference range values according to international instructions. METHODS All results for thyrotropin (TSH) and free thyroxine (T4) that were stored in our laboratory information system between 2004 and 2008 were included ...
متن کاملPrerequisites for use of common reference intervals.
The theory of reference values was developed more than 30 years ago, but its application in most clinical laboratories is still incomplete today. This is for several reasons, the most relevant ones being the lack of standardisation of the analytical methods, resulting in method-dependent values, and the difficulty in recruiting the proper number of reference subjects for establishment of refere...
