7 Things You Must Know Before a Blood Test!
The disease is an unpleasant word and often means blood tests. As new viruses and bacteria are discovered daily, reliance on diagnostics has increased tremendously. The most basic diagnostic is undoubtedly a blood test. A blood sample is collected by a phlebotomist (a person who pricks the needle…. ouch!).
Though blood test seems routine, improper handling could lead to unwanted infection, and in some cases, even more severe illness. Thus it is necessary to take precautions. Always keep in mind the following 7 points before your next blood test.
Preparation and Precautions before a blood test
Check the Reputation of Your Lab and its certification
The system, processes and methodology of labs are great determiners of the quality of blood tests and the results thereof. Though it is difficult to be assured about the quality, one should always look for trusted and certified labs. NABL and CAP are the two most renowned and coveted certifications which ensure that labs follow a proper quality protocol.
Hygiene and Glove use
The phlebotomist should always wash his hands and use a new hand glove before taking the blood sample. This ensures that infection of any other person including a Phlebotomist should not transfer to you.
Use of Proper Labeling
Proper labelling of the sample tube/container is essential to avoid mixing the sample and erroneous reports.
Skin Antisepsis before taking the Sample
The phlebotomist should place gauze or cotton on the punctured site and press it gently. It should be kept pressed for at least 1 to 2 minutes to avoid the formation of a haematoma. Always ask Phlebotomist to apply a band-aid or tape on the punctured site. Blood should be mixed gently with the anticoagulants by inverting the blood collection tube several times.
Proper disposal of waste
You should ensure proper disposal of medical waste by phlebotomists. Most important is the destruction of the syringe to avoid its reuse.
