General Guidelines

  • Each blood collection card and lancet is for one-time use only.
  • Avoid strong repetitive pressure (‘milking’) on the pricked finger. This may cause hemolysis or tissue-fluid contamination of the specimen.
  • Do not rub or smear the blood sample.
  • Air dry only.
  • Missing or incomplete information on the test requisition form will delay the processing time of your specimen.
  • Allow a sufficient quantity of blood to soak through to completely fill in the preprinted circle on the filter paper.
