Determining the rate and reasons for specimen rejection among specimens referred for HIV viral load determination through referral linkage to Debre Tabor Comprehensive Specialized Hospital, north-central, Ethiopia,2023: Retrospective study

Heliyon
Background: The preanalytical phase encompasses the time between the clinician's test order to the sample being ready for analysis. Of all errors during the laboratory diagnostic process,70 % appeared in the pre-analytical phase. In clinical laboratories,

Association of Vitamin B6 and Homocysteine–ACTH Coupling With Depressive and Anxiety Symptoms in Burning Mouth Syndrome: An Exploratory Case–Control Study

Journal of Oral Rehabilitation, Volume 53, Issue 11, Page 2053-2063, November 2026.
In this exploratory case–control study, plasma PLP (vitamin B6), homocysteine and ACTH concentrations did not differ between patients with burning mouth syndrome (BMS) and controls, and none discriminated patients individually. Within patients, however, psychological distress mapped onto a homocysteine–ACTH relationship from which PLP appeared ...

Evaluation of thyroglobulin autoantibodies in dogs at the time of diagnosis of hypoadrenocorticism and during treatment

Veterinary Record, Volume 199, Issue 8, Page e350-e358, 17/24 October 2026.
Abstract Background Autoimmune thyroiditis (AIT) may occur more frequently in dogs with hypoadrenocorticism (HA) than previously recognised. The objective of this study was to determine the presence of thyroglobulin autoantibodies (TgAAs) in dogs with HA.

Evaluation of specimen rejection rates in the preanalytical phase and nurses’ experiences: a mixed design study

BMC Nursing
Background The preanalytical phase is considered the most error-prone part of laboratory testing and significantly contributes to medical errors. Specimen rejections during this phase can delay diagnosis and treatment, compromise patient safety, and ...

Medical errors: Pre-analytical issue in patient safety [PDF]

Journal of Medical Biochemistry, 2010
The last few decades have seen a significant decrease in the rates of analytical errors in clinical laboratories, while a growing body of evidence demonstrates that the pre and post-analytical steps of the total testing process (TTP) are more error-prone
