Q

What is the normal reference range for _____?

If this is elevated, could mean ________?

Which drugs increase this lab value?

Which dugs decrease this lab value?

A
41
Q

When the WBC is elevated, it generally tells us an infection may be present. However, we need more information to be sure that. So, we can order a WBC Differential, which is a ______________.

This includes:

A

differential of our WBCs with all the different components of them broken down for us.

Neutrophils
Bands
Eosinophils
Basophils
Lymphocytes
Monocytes

42
Q

Understanding when one of each of the components is elevated and what that means will be helpful.

Neutrophils
Bands
Eosinophils
Basophils
Lymphocytes
Monocytes

A

Neutrophils -if elevated, indicative an infection is present.

Bands (immature neutrophils) - if elevated “left shit” released early and are indicative an infection is present.

43
Q

Neutrophils & Bands are used together to calculate a ________

A

(ANC) Absolute Neutrophil Count

44
Q

How do you calculate ANC?

A
45
Q

A RBC Differential includes:

sometimes a RBC Differential is also called a _________

A

-RBC
-Hgb
-Hct

“RBC Indices”

46
Q

When Hgb & Hct are low, essentially means patient has ______. So then we have to figure out the cause of this by getting a RBC differential and seeing those values for _____

A

anemia

  • MCV (Mean Corpuscular Volume)
  • MCHC
  • RDW
47
Q

(MCV) Mean Corpuscular Volume, tells you ______

A

the size of the cells

48
Q

When the MCV is low, it means:

A

the cells are small (microcytic)

commonly caused by iron deficiency

49
Q

When MCV is large, it means:

A

the cells are large (macrocytic)

commonly caused by B12 and Folate deficiency

50
Q

Hct = Hgb x 3

A

Knowing the Hemoglobin (Hgb) value & just multiplying by 3 will give you the hematocrit (Hct).

51
Q

Different tests used for different types of anemia

-Coombs Test
-G6PD Deficiency

A
52
Q

A Coombs Test:
-used when hemolytic anemia is suspected
—the RBCs are destroyed faster than the bone marrow can produce them

  • Indicates whether ____________
  • Used to differentiate __________
A

patient is making antibodies against RBCs

autoimmune vs drug induced hemolysis

53
Q

If Test is + for Coombs test, then drug that may be causing problem should _____

A

be discontinued.

54
Q

Examples of drugs that can be + on a Coombs test:
