摘要：This study investigated the influence of long-term storage, for periods up to 24 months, and multiple freezing and thawing on the measured values of lipoprotein[a] (Lp[a]), apolipoproteins B and A-IV, total and high density lipoprotein (HDL) cholesterol and triglycerides using plasma samples stored at -80 degrees C, -20 degrees C, and 4 degrees C. Samples stored at -80 degrees C or -20 degrees C showed significant changes in Lp[a] after 24 months, with a mean decrease of 7% and 13%, respectively (P
