How can a tourniquet effect the result to a blood test?
Venous blood sampling is usually performed using a tourniquet to help locate and define peripheral veins to achieve successful and safe venipuncture. Despite widespread usage of tourniquets for venipuncture by medical and laboratory staff, very few are aware of the effects of tourniquet application on laboratory parameters. In addition, definitive guidelines regarding when and how to use a tourniquet for blood sampling are lacking. It can cause the blood to pool and negatively affect any results including: cholesterol levels glucose liver hemogolbin to name a few Also it can be affected by posture i.e. if sitting for 30 minutes before or lying down.
A phlebotomist must collect a blood specimen from an isolation patient with contact transmission precautions What is the best type of tourniquet to use to perform the venipuncture and why?
For a patient under contact transmission precautions, the best type of tourniquet to use is a disposable, single-use tourniquet. This minimizes the risk of cross-contamination and infection, as it can be discarded immediately after use, preventing the spread of pathogens. Additionally, using a disposable tourniquet aligns with infection control protocols in isolation settings.

When venipuncture is performed using a lavender vacutainer tube, the sample collected is typically used for hematology testing, such as complete blood count (CBC), erythrocyte sedimentation rate (ESR), and blood typing. The lavender top tube contains EDTA as an anticoagulant to preserve the blood sample for these types of tests.
Can a tourniquet cause a blood clot?
A tourniquet can potentially contribute to the formation of a blood clot if it is applied improperly or left on for an extended period. The pressure can restrict blood flow, leading to stasis, which is a risk factor for clot formation. However, in emergency situations, the benefits of using a tourniquet to control severe bleeding typically outweigh the risks. Proper application and timely removal are crucial to minimize complications.
Why you should sterilize the venipuncture site of the blood donor by using both of iodine and alcohol?
There are many reasons to sterilize the venipuncture site of a blood donor using both iodine and alcohol. The main concern and reason to do this is sanitation and bacteria transfer. By sanitizing the area and the needle, bacteria are less likely to enter the puncture wound and infect a donor's bloodstream.

How do you overcome incomplete blood collection during venipuncture?
To overcome incomplete blood collection during venipuncture, first ensure proper technique by using an appropriate-sized needle and selecting the correct site on the vein. If blood flow is slow or stops, gently reposition the needle or apply slight pressure above the puncture site to help increase blood flow. Additionally, ensure the patient is well-hydrated and relaxed, as anxiety or dehydration can affect blood collection. If issues persist, consider using a different site or consulting with a more experienced colleague.
