Background A patient survey developed by the Pre-Analytical Phase Special Interest Group of the Association for Clinical Biochemistry and Laboratory Medicine (ACB-PA-SIG) was conducted during November and December 2019. The survey aimed to determine the quality of information provided to patients in preparation for their blood test(s). In addition, the ACB-PA-SIG provide a number of recommendations, which, if adopted, may yield higher quality test results and improve patient management. Methods The survey was distributed at phlebotomy suites in two Hospitals: Ipswich Hospital (United Kingdom [UK]), and Cork University Hospital (Republic of Ireland [RoI]). Results Overall, 235 survey responses were received from the two sites. A total of 103 respondents received no information about preparing for their blood test and 92 had been told they did not need to fast. None of the patients surveyed had been instructed to fast for 12 h. Twenty-two patients had been told to avoid certain foods, drinks or medication, 14 were told to avoid strenuous activity and 41 respondents had been informed of the need to avoid alcohol/smoking prior to their blood test. Overall, only approximately 78 felt well informed about the blood taking process. Conclusions Based on the results of this survey, the ACB-PA-SIG conclude that: (1) clinicians should provide clear written information to patients regarding pre-analytical requirements; and (2) effective communication between laboratories and General Practitioners is required to disseminate information. In this paper, the ACB-PA-SIG provide a list of pre-analytical recommendations to standardize and improve practice across the UK and RoI.

Furthermore, laboratory medicine professionals, motivated to eliminate fasting time based on their convenience, 27 must be aware that this represents more risks than benefits for patients. 28…”

Laboratories worldwide perform both hematological and coagulation testing on patients avoiding fasting time. In 2017, the Latin America Confederation of Clinical Biochemistry (COLABIOCLI) commissioned the Latin American Working Group for Preanalytical Phase (WG-PRE-LATAM) to study preanalytical variability and establish guidelines for preanalytical procedures to be applied by clinical laboratories and health care professionals. This study, on behalf of COLABIOCLI WG-PRE-LATAM, aims to evaluate the effect of the breakfast on routine hematology and coagulation laboratory testing. We studied 20 healthy volunteers who consumed a breakfast containing a standardized amount of carbohydrates, proteins, and lipids. We collected blood specimens for routine hematology and coagulation laboratory testing before breakfast and 1, 2, and 4 hours thereafter. Significant differences between samples were assessed by the Wilcoxon ranked-pairs test. Statistically significant differences (p < 0.05) between basal and 4 hours after the breakfast were observed for red blood cells, hemoglobin, hematocrit, mean corpuscular volume, white blood cells, neutrophils, lymphocytes, monocytes, mean platelet volume, and activated partial thromboplastin time. In conclusion, the significant variations observed in several hematological parameters, and activated partial thromboplastin time due to breakfast feeding demonstrate that the fasting time needs to be carefully considered prior to performing routine hematological and coagulation testing to avoid interpretive mistakes of test results, and to guarantee patient safety. Therefore, COLABIOCLI WG-PRE-LATAM encourages laboratory quality managers to standardize the fasting requirements in their laboratory, i.e., 12 hours.
