00:01
So let's get started
with lab work.
00:03
I want to start with the CBC,
one of my favorite lab tests
because you can learn so
much about your patient.
00:10
But in particular we're
going to be looking for
the level of white blood cells.
00:15
So I'm going to be assessing
for an elevated white
blood cell level or
leukocytosis.
00:21
So I'll look for
any abnormal values,
but if I'm looking
at cholecystitis,
I'm particularly interested
in the white blood cell level.
00:30
Now the normal range for
white blood cells is 5 to 10.
00:34
Now you notice we
have 10 to the third.
00:36
I want you to know when
you're in the hospital.
00:38
You may hear a nurse say
their level is 5 but what
they really mean is 5,000.
00:44
You may hear him say it's 8,
white blood cells are 8 and
that really means 8,000.
00:49
So that's how we speak it,
but what you see
on the screen is
what you'll see in the results.
