Interpreting lung function data using 80% predicted and fixed thresholds misclassifies more than 20% of patients.

TL;DR: This document presents a reporting format in test‐specific units for spirometry, lung volumes, and diffusing capacity that can be assembled into a report appropriate for a laboratory's practice that can improve the interpretation, communication, and understanding of test results.

TL;DR: NGAL measured at ICU admission predicts the development of severe AKI similarly to serum creatinine-derived eGFR, however, NGAL adds significant accuracy to this prediction in combination with eG FR alone or with other clinical parameters and has an interesting predictive value in patients with normal serum creat inine.

TL;DR: Maximum mid-expiratory flow and flow towards the end of the forced expiratory manoeuvre do not contribute usefully to clinical decision making over and above information from FEV1, FVC and FEV 1/FVC ratio.

TL;DR: The aim of this study was to determine the contribution of secular trends and sample size to lung function reference equations, and establish the number of local subjects required to validate published reference values.

TL;DR: This section is written to provide guidance in interpreting pulmonary function tests (PFTs) to medical directors of hospital-based laboratories that perform PFTs, and physicians who are responsible for interpreting the results of PFTS most commonly ordered for clinical purposes.

TL;DR: Assessing the total lung capacity is indispensable in establishing a restrictive ventilatory defect or in diagnosing abnormal lung distensibility, as may occur in patients …

TL;DR: The main goals of the updated document are to improve the quality of care provided to patients with COPD and to develop the project using a disease-oriented approach.
