Haemolysis rates in emergency department samples are higher than those in inpatient or outpatient settings. This study evaluated the association between phlebotomy techniques and haemolysis rates in the emergency department.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Blood samples collected in the emergency department with documented phlebotomy technique between November 2023 and September 2024 were audited. Five phlebotomy methods were compared: [1] needle\/butterfly to vacutainer (closed system), [2] syringe-needle draw, [3] syringe draw from an intravenous cannula, [4] vacutainer collection from cannula using an adapter, and [5] use of a discard tube for either needle or cannula draws. Haemolysis was defined by an Abbott Alinity H-index \u22651.25 (\u22481.25\u00a0g\/L free haemoglobin), above which potassium results are suppressed by the laboratory.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 586 samples, 42 (7.2%) were haemolysed. Haemolysis rates were 16.7% (2\/12) for syringe draw from intravenous cannula, 14.8% (31\/209) for vacutainer collection from intravenous cannula using an adapter, 6.3% (1\/16) for syringe-needle draw, 2.4% (2\/83) for methods using a discard-tube in either needle or cannula collection, and 2.3% (6\/266) for needle\/butterfly to vacutainer closed phlebotomy method. Haemolysis differed significantly by method (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.0001): draws from cannula using adapter had higher rates than closed phlebotomy (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.0001) and discard-tube draws (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.0017).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Closed phlebotomy methods, particularly needle or butterfly collection into vacutainer tubes, were associated with the lowest haemolysis rates.
