POC
What does POC stand for and what is the definition?
Point of Care is any lab test performed outside of the laboratory, typically at the bedside.
Which tube do you draw first?
Cultures
A1Cs are a test used to indicate what chronic disease?
Diabetes
A lipid panel typically consists of four tests:
Total cholesterol
HDL cholesterol
LDL cholesterol
Triglycerides
This is the amount of times all tubes should ultimately be inverted
What is 8-10 times?
What does the "C" stand for on a POC cartridge?
Internal Control.
What all do you need to document on a tube?
Pt name, DOB/MRN, Test Name, Collection Date and Time, Phlebotomist's Initials
Which specimen collection method would you use for an A1C test?
Capillary puncture or lavender tube
What are the normal ranges for a lipid panel?
Total cholesterol: Less than 200
HDL cholesterol: 50 and higher
LDL cholesterol: Less than 130
Triglycerides: Less than 200
When you draw blood what 3 main components are you collecting in the tube?
Plasma ~55%, Buffy Coat <1%, Erythrocytes ~45%
What two things do you need to note from each point of care cartridge?
Lot number and expiration date.
You have the following tubes: Grey, Tiger, Green.
What is the order of draw?
Tiger, Green, Grey
What are the the normal, prediabetic, and diabetic ranges of A1C?
Normal is less than 5.7%
Prediabetic is 5.8-6.5%
Diabetic is more than 6.5%
What is an HDL particle?
High-Density Lipoproteins (HDL) are known as “good cholesterol”, because their job is to transport excess cholesterol and bring it to the liver for disposal. It is removed from the blood in this way, so does not encourage plaque build-up.
What do clot activators yield?
Serum
What is the difference between EXP and BUD
Exp is the manufacture expiration date. BUD is the beyond use date. Both of which should be clearly labeled on POC supplies. Specifically on multi-use vials.
Sodium and Lithium Heparin can be found in this color tube
Green and light green
Does the patient need to be fasting for an A1C test?
The patient is not required to be fasting for a HgA1c test
What is an LDL particle?
Low-density Lipoproteins (LDL) transport cholesterol through the rest of the body, which is incredibly important. However, chronically elevated LDL cholesterol levels are commonly associated with plaque build-up, atherosclerosis and other forms of vascular damage, For this reason, LDL is often referred to as “bad” cholesterol.
What do anticoagulants yield?
PLASMA or WHOLE BLOOD, depending on the additive type.
Describe the location of the capillary puncture site (adult finger)
Finger punctures should be performed near the outer 1/3 of the fleshy portion of the distal phalanx on the palmar surface. 3rd or 4th digit.
These are the names of the three anticoagulant tubes, in order of draw, which do not yield whole blood
What are light blue, green and grey
What is a A1C test measuring specifically?
The HbA1c test measures the average glycated hemoglobin amount on RBCs.
How quickly do you need to fill the capillary tube?
The capillary tube should be filled within 10 seconds. Do not allow any bubbles to enter the capillary tube.

Cultures, Light Blue, Red/Gold/Tiger, Green, Lavender, Grey
