Why can’t you draw blood above an IV site?
Blood that is drawn from a vein that has an intravenous (IV) line may be diluted by the IV fluid. This can ultimately affect the accuracy of the blood test results. Therefore, an arm containing an IV should not be used to draw blood specimens if it can be avoided.
When drawing blood above an IV line you must?
The only coagulation test that can be drawn above an IV site is the prothrombin time. The infusion should be turned off for 10 minutes before obtaining this coagulation test. (A discard tube is still necessary.) For blood cultures, there is no need to discard any blood prior to filling the culture tubes/bottles.
Can you draw blood from peripheral IV?
A. Blood samples should NOT be drawn during IV starts or from established IV catheters except for patients on thrombolytics (to reduce number of sticks), or in an emergency. B. Peripheral lab samples should be obtained using a straight needle and either the Vacutainer or syringe method.
Which of the following tubes should be drawn first?
The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.
Does IV go in artery or vein?
IVs are always placed in veins, not arteries, allowing the medication to move through the bloodstream to the heart. Learn more about IVs by reading 10 Commonly Asked IV Therapy Questions.

Why should you follow the correct order of draw during phlebotomy?
The order of draw is recommended for both glass and plastic venous collections tubes when drawing multiple specimens for medical laboratory testing during a single venipuncture. The purpose is to avoid possible test result error due to additive carryover.
How do you remember the order of draw?
A mnemonic device is a phrase or saying that is easy to remember and relate back to in the future. It’s a great way to remember order of draw (OOD) because you can modify the sentence to be most helpful to you. In this example, the tubes that make the order of draw are identified by color.

How do you know if its a vein or artery?
Arteries = high pressure, veins = low pressure. If you cut yourself and an artery is bleeding, it squirts a long way and it will have a pulse. If a vein is bleeding, the sight of it will still be disturbing, but it will not be pulsatile and it will be low pressure.
How do you know if your IV is in an artery?
Signs of suspected arterial puncture include noting bright red blood with pulsatile flow, blood column moving upwards in the tubing of an infusion set, intense pain and distal ischaemia. [5] Confirmation is carried out by blood gas analysis, pressure transducer and ultrasound.

How is phlebotomy performed?
Phlebotomy is when someone uses a needle to take blood from a vein, usually in your arm. Also called a blood draw or venipuncture, it’s an important tool for diagnosing many medical conditions. Usually the blood is sent to a laboratory for testing.
What color tube for lab draws?

What is the important step in phlebotomy?
Venipuncture is the process of collecting or “draw- ing” blood from a vein and the most common way to collect blood specimens for laboratory testing. It is the most frequent procedure performed by a phle- botomist and the most important step in this proce- dure is patient identification.
