Veins are the preferred choice for drawing blood samples because they are closer to the surface of the skin, making them easier to access. Additionally, veins have a larger diameter and are more elastic than arteries, which allows for a smoother and less painful blood draw process.
What else can I help you with?
Can you detect chlamydia in blood samples?
Chlamydia is typically detected through urine or swab samples, not blood samples. Blood tests are not commonly used for diagnosing chlamydia.
Is it possible to extract DNA from blood samples?
Yes, it is possible to extract DNA from blood samples. This process involves isolating the DNA molecules from the blood cells and purifying them for analysis or testing.
What are the characteristics and implications of partial hemolysis in blood samples?
Partial hemolysis in blood samples refers to the breakdown of some red blood cells, leading to a pink or red discoloration of the sample. This can affect the accuracy of certain blood tests, as it may release substances that interfere with the results. It is important to properly handle and store blood samples to prevent hemolysis and ensure reliable test results.
What two types of blood specimens are used for most hematological tests?
The two main types of blood specimens used for most hematological tests are whole blood and plasma. Whole blood includes all components of blood, while plasma is the liquid portion of blood after cells have been removed.
Does having food on your finger affect your blood glucose?
Yes it will affect the reading you get (not your actual blood glucose). If you have food (especially sugary food) on your finger where you take the drop of blood from, then the sugar from the food will mix with the blood and give a false reading. This is why it is important to wash the finger before testing blood glucose.
Would blood samples for ammonia require a tourniquet when drawing?
no.
Why is EDTA the preferred anticoagulant?
EDTA is the preferred anticoagulant for blood samples because it chelates divalent cations like calcium and magnesium, preventing blood from clotting by inhibiting the coagulation cascade. It helps preserve the integrity of blood samples for laboratory analysis by preventing clot formation. Additionally, EDTA does not interfere with most laboratory tests, making it a versatile anticoagulant choice.
Which vein used for taking blood samples?
There are three veins to choose from when drawing blood. The first choice is Median Cubital. Second is Cephalic vein and lastly the Basilic vein.
What do most phlebomotist do?
Their despciption is drawing blood from patients for example a patient that has medicanion like coumadin (a blood thinner) or just a simple blood draw for the lab to test. Also they administer stool samples and urine samples.
What color tube is drawn for a hgb electrophoresis?
A lavender-top (EDTA) tube is typically used for drawing blood samples for hemoglobin electrophoresis testing.
Sodium fluoride is the anticoagulant choice for?
Sodium fluoride is not commonly used as an anticoagulant choice; it is typically used as a preservative in blood samples for glucose testing. Common anticoagulants used for blood collection include EDTA, heparin, and citrate.
Can you detect chlamydia in blood samples?
Chlamydia is typically detected through urine or swab samples, not blood samples. Blood tests are not commonly used for diagnosing chlamydia.
When was Drawing Blood created?
Drawing Blood was created in 1993.
How many pages does Drawing Blood have?
Drawing Blood has 416 pages.
What does sodium citrate do when drawing blood samples?
Sodium citrate is an anticoagulant that is added to blood collection tubes to prevent the blood from clotting. It works by binding to calcium ions in the blood, which are necessary for the clotting process, and thereby inhibiting blood clot formation during sample collection and processing.
When drawing blood by the Vacationer method it is important to fill the tubes in the recommended order. which tube would be filled first?
The yellow tube (sterile) should be filled first when drawing blood using the Vacutainer method. It is crucial to follow the recommended order to prevent contamination of samples and ensure accurate test results.
What samples need to be run 15 minutes apon drawing ptt ABG PKU?
For tests such as PTT (Partial Thromboplastin Time), ABG (Arterial Blood Gas), and PKU (Phenylketonuria), it is crucial to run the samples promptly after drawing to ensure accuracy. Specifically, ABG samples should be analyzed within 15 minutes to prevent changes in gas levels due to metabolism. Similarly, PTT samples should be processed quickly to ensure reliable coagulation results, while PKU samples should ideally be analyzed as soon as possible to maintain the stability of the metabolites being measured.
