Physician office lab
Can range from simple screening tests done in single practice office or specialized testing done in large group settings
Reference lab
These large independent lab preform routine and highly specialized tests that cannot be done in smaller ones. The phlebotomist may do either on-site or off site collection.
Characteristics imperative to a phlebotomist?
Dependability
Honesty

The function of the circulatory system is to do what?
Deliver oxygen, nutrients, hormones, and enzymes to the cells
The exchange of oxygen, nutrients, hormones and enzymes is done where in the circulatory system
The exchange is done at the capillary level
After the capillary level exchange where are waste taken to and expelled from
Waste such as, carbon dioxide and urea are taking to the organs (lung, kidneys) they can be expelled from the body.
The circular Tory system is known as what in the body?
The transport system.
Blood is the vehicle, the blood vessels, the two and the heart work is the pump
Pulmonary circulation is which pump in the series
This carries deoxygenated blood from the right ventricle to the lungs and returns oxygenated blood from the lungs to the left atrium
The systemic circulation in the series hearts 2 pumps is
To carry oxygenated blood from the left ventricle throughout the body
What is the liquid portion in the composition of blood
Plasma
Plasma comprises 55% of the circulating blood and contains proteins, amino acids, gases, electrolytes, sugar, hormones, minerals, vitamins and 92% water
Plasma also contains a cellular portion called the ‘formed elements’
What do the formed elements in blood constitute
The remaining 45% of blood.
There are Erythrocytes (red blood cell), which comprise 99% of the formed elements, leukocytes (white blood cells), and thrombocytes (platelets)
Do you erythrocytes contain hemoglobin
Yes
What is the lifecycle of a erythrocytes
It enters the blood as an immature reticulocyte and within 1 to 2 days it matures into a erythrocyte
There are 4.2 to 6.2 million RBCs per microliter of blood.
The normal lifespan of an RBC is 120 days
What is the function of a leukocyte
To provide the body protection against infection
What is the normal amount of leukocytes (WBC) for an adult
5000 to 10,000 per microliter
What is leukocytosis
An increase in the WBC as seen in infections and leukemia
What is leukopenia
A decrease in WBC as seen with a viral infection or chemotherapy
What are the five types of leukocytes (WBC) in the blood
Neutrophils
Lymphocytes
Monocytes
Eosinophils
Basophils
What is a neutrophil
The most numerous white blood cells, comprise 40% to 60% of WBC population.
They are phagocytic cells (engulf and digest) & increase in numbers during bacterial infection and are often the first on the scene
Lymphocytes are what
The second most numerous white blood cells, comprising about 20% to 40% of the WBC population
They increase in numbers during a viral infection and they play a role in immunity
Monocytes are what
Comprising 3% to 8% of the population, they are also the largest WBC.
Monocytes while circulating in the blood can pass through tissue they transform into microphage him become powerful phagocytes
The numbers increase in intracellular infections and tuberculosis
