  2. 1. Preanalytical errors in hospitals : implications for quality improvement of blood sample collection

    Author : Olof Wallin; Christine Brulin; Kjell Grankvist; Johan Hultdin; Bethany van Guelpen; Ania Willman; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical errors; preanalytical; quality improvement; questionnaire; venous blood sampling; Clinical chemistry; Klinisk kemi;

    Abstract : Background: Most errors in the venous blood testing process are preanalytical, i.e. they occur before the sample reaches the laboratory. Unlike the laboratory analysis, the preanalytical phase involves several error-prone manual tasks not easily avoided with technological solutions. READ MORE

  4. 2. Sources of preanalytical error in primary health care : implications for patient safety

    Author : Johan Söderberg; Christine Brulin; Ewa Idvall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood specimen collection; haemolysis; medical errors; phlebotomy; preanalytical; primary health care; quality indicators; quality of health care; questionnaires; specimen handling; Clinical chemistry; Klinisk kemi; medicin; Medicine;

    Abstract : Background Venous blood tests constitute an important part in the diagnosis and treatment of patients. However, test results are often viewed as objective values rather than the end result of a complex process. This has clinical importance since most errors arise before the sample reaches the laboratory. READ MORE

  5. 3. Improving venous blood specimen collection practices : method development and evaluation of an educational intervention program

    Author : Karin Bölenius; Christine Brulin; Kjell Grankvist; Johan Söderberg; Ewa Idvall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Education; Experiences; Guideline adherence; Haemolysis; Intervention; Patient safety; Phlebotomy; Practical skills; Preanalytical errors; Primary healthcare; Questionnaires; Reliability and validity; Venous blood specimen collection; omvårdnadsforskning med medicinsk inriktning; Caring Sciences; Clinical Chemistry; klinisk kemi;

    Abstract : Background: About 60%–80% of decisions regarding diagnosis and treatment are based on laboratory test results. Low adherence to venous blood specimen collection (VBSC) guidelines may lead to erroneous or delayed test results, causing patient harm and high healthcare costs. READ MORE

  6. 4. Development and evaluation of immunoassays for complement diagnostics

    Author : Kerstin Sandholm; Kristina Nilsson Ekdahl; Ingvar Ryden; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immune assays; complement diagnostics; xMAP-technology; C1q; preanalytical factors; method validation; Immunologi; Immunology;

    Abstract : Laboratory analyses of human body fluids play an important role in clinical diagnosis. This thesis comprises projects in which various immune assays have been developed and evaluated as complement diagnostics in both plasma and cerebrospinal fluid (CSF). READ MORE

  7. 5. Stability of zopiclone in whole blood : Studies from a forensic perspective

    Author : Gunnel Nilsson; Robert Kronstrand; Johan Ahlner; Fredrik Kugelberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Bio‐analytical results are influenced by in vivo factors like genetic, pharmacological and physiological conditions and in vitro factors like specimen composition, sample additives and storage conditions. The knowledge of stability of a drug and its major metabolites in biological matrices is very important in forensic cases for the interpretation of analytical results. READ MORE
