INTRODUCTION Preanalytical errors still constitute the largest source of errors in laboratory work. Proper patient preparation and patient's knowledge about a particular procedure affects its accuracy and reliability. We hypothesized that most of pregnant women are not well enough informed about the proper procedure for the OGTT. The aims of this study were to investigate: (i) how well pregnant...

It is unknown if high prolactin levels during pregnancy contribute to the development of gestational diabetes. We hypothesized that higher prolactin levels are associated with reduced glucose tolerance, as determined by higher 2-h glucose level from an oral glucose tolerance test in pregnancy. The 75-g oral glucose tolerance test was carried out at 28 weeks of gestation in 69 participants. A mu...

The diagnostic criteria for diabetes have been recently revised and the fasting plasma glucose (FPG) level reduced to 126 mg/dL, since the earlier cutoff of 140 mg/dL was considered to correspond to a much higher level than the 2-hour postglucose (2 h PG) value of 200 mg/dL. However, there are few data directly correlating FPG and 2 h PG during an oral glucose tolerance test (OGTT). This study ...

Aim: The goal of this study was to establish the level awareness amongst pregnant women in terms preparation for an oral glucose tolerance test (oGTT), compare results two waves data collection, and identify most frequent preanalytical mistakes made connection oGTT. Design: Comparison 2 cross-sectional studies. Methods: From 2013–2017 independent questionnaire studies were performed on a ...

OBJECTIVES To evaluate the applicability of the 50-g glucose challenge test as a screening test for gestational diabetes mellitus in relation to pregnancy outcomes. METHODS A prospective study was conducted on 818 Saudi pregnant females who were randomly recruited from the Antenatal Clinics at King Abdulaziz University Hospital and New Jeddah Clinic Hospital, Jeddah. All females underwent a 5...

OBJECTIVES This study evaluated a simple relaxation breathing exercise for acute improvement of postprandial glycemic and insulinemic status. DESIGN Healthy human subjects were randomized to control breathing (CB; n=13) or a relaxation breathing exercise (RB; n=13) that was repeated every 10 minutes for the 30 minutes before and 90 minutes after consuming a glucose challenge (oral glucose tol...
