This question is related with the article written by Neuwinger, Nick et al. entitled “Underfilling of vacuum blood collection tubes leads to increased lactate dehydrogenase activity in serum and heparin plasma samples,” by examining the impact of blood collection techniques (venipuncture vs. IV catheterization) on hemolysis index and potassium concentration in samples. I seek to understand its implications for sample quality and laboratory testing.
The impact of different blood collection methods, such as intravenous catheterization versus venipuncture, on the potassium concentration and hemolysis index in serum and heparin plasma samples are observed. Comprehending these distinctions is essential for evaluating sample quality and guaranteeing dependable laboratory testing outcomes. When interpreting hemolysis and potassium levels, laboratories should take the technique of blood collection into account. Appropriate quality control procedures should be put in place to minimize pre-analytical impacts and preserve the integrity of test results.
