Objectives: The research was conducted as a descriptive study to evaluate the practices and knowledge levels of mid-wives and nurses in the preanalytical phase of newborn screening tests.Methods: The sample of the study consisted of 233 midwives and nurses working in 90 primary healthcare centers in three major districts of Istanbul. The practices and knowl-edge levels of the participants in the preanalytical phase of blood sampling were evaluated with the Preanalytical Phase Evaluation Form [PPEF].Results: It was determined that only 43.3% of the partici-pants comforted the baby before taking the blood sample, and 61.8% paid attention to the temperature of the heel. Furthermore, 56.2% continued to fill the same circle on the screening card by squeezing the heel due to inadequate blood, 62.7% ensured the blood completely soaked through the front and back of the card, and 36.1% used both sides of the card to fill the circles. Only 53.6% of the participants stored the dried blood samples in the fridge. The mean PPEF knowledge score of the participants was 14.64 +/- 3.40. There were statistically significant differences in the knowledge scores of midwives and nurses according to age, educa-tional level, and working year (p < 0.05).Conclusions: In the study, it was determined that the practices of nurses and midwives in the preanalytical phase were not at a good level. In particular, it is recom-mended that nurses and midwives who are younger, have a lower educational level, and work fewer years be super-vised and supported with training.
