Why do you draw a discard tube before a blue tube?
Drawing a discard tube before a blue tube in blood collection prevents contamination with tissue fluids or substances that could affect test results. The discard tube helps clear the line of air and ensure that the blood sample collected in the blue tube is free from any potential contaminants.
What accrues if a gray stopper tube is collected before a lavender shield tube?
Orange shield tube is usual for infectious disease tests. Blue top may be used for many types of test.
What color tube is used for Platelet function studies?
Platelet function studies are typically collected in a blue-top tube (sodium citrate) to prevent clotting and maintain the function of platelets for analysis.
What color tube should be collected for CBC?
A lavender-top tube should be collected for a complete blood count (CBC).

What color tube for haptoglobin?

What tube use for Digoxin level?
A red top tube (serum separator tube) is typically used to collect blood for digoxin level testing. The tube should be inverted gently to mix the blood with the anticoagulant and clot activator present in the tube. Once the sample is collected, it should be processed promptly to separate the serum for analysis.
What can happen if a lavender tube is collected before a light green tube?
If a lavender tube is collected before a light green tube, there is a risk of contamination and carryover of additives present in the lavender tube into the sample collected in the light green tube. This can affect the accuracy of test results and potentially lead to erroneous findings. It is important to follow the correct order of draw to ensure the integrity of the samples.
