The coming of age of liquid chromatography coupled to tandem mass spectrometry in the endocrinology laboratory

Carvalho, Valdemir Melechco·2012·Journal of Chromatography B

Abstract

Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) has been rapidly incorporated in the routine of the endocrinology laboratory. Most endocrinologists are aware of the benefits afforded by this technique and tandem mass spectrometers are clearly no longer a mere research method but an important tool widely used for diagnosis. In the last 15 years, LC-MS/MS has replaced techniques such as immunoassay and HPLC for the analysis of hormones because it provides higher specificity and good sensitivity. Also, it permits simultaneous measurement of several analytes and sample preparation and acquisition are fast and simple. Although several strategies based on LC-MS/MS have been described in the last 15 years, there is still room for improvement. The impact of matrix effects and isobaric interferences have been addressed by only a few studies, and standardization with reference materials is available for a limited number of analytes. This review summarizes the application of LC-MS/MS in analyzing three classes of hormones: steroids, derivatives of the aromatic amino acids, and peptides and proteins. The benefits and current limitations of LC-MS/MS will be discussed for these hormone categories.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Additional factors that may account for variability include specimen handling and preparation, calibration methods, specimen commutability, and interference from matrix material used to store and transport testosterone preparations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
