Detectable Laboratory Abnormality Is Present up to 12 Months Prior to Diagnosis in Patients with Crohn's Disease.

Background And Aims: Patients with inflammatory bowel disease (IBD) often have subjective symptoms for months or years prior to their diagnosis. Blood tests taken prior to diagnosis may provide objective evidence of duration of pre-diagnosis disease. We aim to describe the pre-diagnosis laboratory pattern of patients with IBD.

The kinetics of haemoglobin and ferritin in longitudinal community patients with iron deficiency or hypoxia.

Background: Red cell distribution width (RDW) is well recognised as a marker of iron-deficient anaemia, as well as useful to the distinction between some anaemic states. A role in the prediction of patient mortality and for the laboratory diagnosis of organ dysfunction has been also investigated. RDW has recently been suggested as a marker of acute and chronic hypoxia.

The early detection of anaemia and aetiology prediction through the modelling of red cell distribution width (RDW) in cross-sectional community patient data.

Background: Red cell distribution width (RDW) is a marker of iron-deficient anaemia that can also assist differentiation of other anaemias. RDW also has been suggested as an effective marker for earlier anaemia detection. The RDW-anaemia relationship was investigated in cross-sectional community patient data, and the capacity of RDW to predict the diagnostic value of second tier anaemia markers assessed.
