When should a vacutainer/collection tube be mixed?

Immediately after drawing blood
within 30sec of drawing blood
After 1 minute of drawing blood
Mixing is not required

The correct answer is: within 30sec of drawing blood

After drawing blood, the vacutainer/collection tube should be mixed within 30 seconds. This agitation ensures that the blood and any anticoagulant or additive are properly mixed, preventing clotting or other issues with the sample. Mixing immediately or waiting too long after drawing can cause inaccurate or unreliable results. Therefore, options A, C and D are incorrect as they do not align with proper blood handling and can lead to compromised samples.
