AB  - BACKGROUND: Preanalytical mistakes (PAMs) in samples usually led to rejection 
      upon arrival to the clinical laboratory. However, PAMs might not always be 
      detected and result in clinical problems. Thus, PAMs should be minimized. We 
      detected PAMs in samples from Primary Health Care Centres (PHCC) served by our 
      central laboratory. Thus, the goal of this study was to describe the number and 
      types of PAMs, and to suggest some strategies for improvement. METHODS: The 
      presence of PAMs, as sample rejection criteria, in samples submitted from PHCC to 
      our laboratory during October and November 2007 was retrospectively analysed. 
      RESULTS: Overall, 3885 PAMs (7.4%) were detected from 52,669 samples for blood 
      analyses. This included missed samples (n=1763; 45.4% of all PAMs, 3.3% of all 
      samples), haemolysed samples (n=1408; 36.2% and 2.7%, respectively), coagulated 
      samples (n=391; 10% and 0.7%, respectively), incorrect sample volume (n=110; 2.8% 
      and 0.2%, respectively), and others (n=213; 5.5% and 0.4%, respectively). For 
      urine samples (n=18,852), 1567 of the samples were missing (8.3%). CONCLUSIONS: 
      We found the proportion of PAMs in blood and urine samples to be 3-fold higher 
      than that reported in the literature. Therefore, strategies for improvement 
      directed towards the staff involved, as well as an exhaustive audit of 
      preanalytical process are needed. To attain this goal, we first implemented a 
      continued education programme, financed by our Regional Health Service and 
      focused in Primary Care Nurses.
