Errors that can happen during sample collection

Here are different types of errors that can happen during the sample collection procedure at home that can affect your test results. It is important to keep the following things in mind at the time of your sample collection:

  • Inadequate information about the test: You should be well informed about the test prior to the collection. The phlebotomist should inform you about the test and be able to answer basic queries related to the test. For example: for fasting blood samples, knowledge of the same will ensure accuracy.
  • Hushed-up experience: The complete procedure of collecting a blood sample and transporting it to the lab is a systematic affair and has few defined steps to follow. Hence, patience and proper use of equipment is essential. For example, improper use of a tourniquet can affect the results or shaking the sample rigorously can affect the quality of the collected sample or during skin sterilisation prior to the prick, not allowing the alcohol to dry completely can alter test results.
  • Reuse of equipment: For every blood test use of fresh needles is a must. The phlebotomist should open a sealed needle right in front of your eyes. Always check for the same.
  • Mislabelled samples: Blood samples have to be labelled properly for correct identification, investigation and reporting.
  • Hygienic factors: Hygiene is the first and foremost consideration while giving your blood sample. Right from the appearance of the phlebotomist to the equipment used like needles, cotton etc, all should score 1 on hygiene. Check for the following while giving your blood sample:
    The phlebotomist has worn a fresh pair of gloves.
    The work area must be sterile.
    A disposable syringe is being used.
    The area of the skin is cleaned with an antiseptic wipe
  • Insufficient quantity of sample collected: All diagnostic test require a said amount of blood sample, hence adequate quantity is essential for accurate results.
