A. Is its good laboratory practice to alternate between dermal puncture and venipuncture collections on a patient having a glucose test every four hours? ___________ Please explain why or why not:

B. What pre-analytical step must be taken before drawing the patient?

Expert Solution

A. Yes,

it is a good laboratory practice to alternate between dermal puncture and venipuncture collection on a patient having a glucose test every four hours.

Because, dermal puncture is an alternative collection procedure for taking small amount of sample of blood.

These techniques used in patients for who the venipuncture is impossible.

It takes only few amount of blood so easier in multiple blood checking like every four hours.

Dermal puncture used to determine bleeding time also used for determine the blood glucose level.

B. Pre analytical steps includes:

Preparing the work place.
Request to test.
Sanitize hands for safety.
Identify and prepare the patient.
Asseble the needed equipments.
Position the patient.
Apply tourniquet.
Select vein.
Clean the site.
Venipuncture.
Fill tubes.
Remove tourniquet.
Place gauze.
Remove needle and dispose the device properly.
Label the tubes.
Storage.
