00:01
Now, let's take a
look at a urinalysis
of one of the important test
of assessing renal function.
00:07
An in-depth assessment of a
urine sample by a train lab
or health care professional
can tell you a lot
of information
about your patients.
00:14
We can use it to assess for a
UTI a urinary tract infection
kidney problems
or even diabetes.
00:21
Now the healthcare provider may
want to sample a first void.
00:25
That means you're going
to ask the patient to do
the urine sample at home
if they're an outpatient
or in the hospital.
00:30
But it needs to
be the first void.
00:32
That's when they get up in the
morning the first time they pee
that's what we're looking for
because it's more concentrated.
00:39
So if that's
what the healthcare provider wants
will usually include that in the order.
00:43
Now a clean catch urine
sample might also be required
that requires
teaching the patient
how to clean their
urinary tract area,
and that will have to
start their stream.
00:53
Stop it then put
the cup underneath
and get a clean
catch urine sample.
00:58
We're trying to avoid
getting all the skin cells
or other floor into
the urine sample
by cleaning the area very well
starting a stream stop it
and then getting a sample.
01:08
Now we can diagnose
some kidney problems
with a urinalysis
like chronic glomerulonephritis,
nephrotic syndrome,
acute glomerulonephritis,
rapidly progressing
glomerulonephritis,
or asymptomatic
hematuria or proteinuria.
01:23
So these diagnosis can be hinted
that were supported by
looking at a urine analysis
because the urine
Calluses looks at color.
01:32
First of all, yeah, seriously,
but actually look
at the urine sample
and then identify
the type of color.
01:39
The look at the appearance
the hold it up and see
is it clear or is a cloudy.
01:43
Urine without problems
should be clear
if there's floating kind of
hazy milky substance in it.
01:51
Then that's considered cloudy and
usually a sign of some type of infection.
01:55
Also will look at the odor.
01:57
This would not be my favorite
job to get to smell the urine,
because there's some pretty
intense smells that can be made.
02:04
So first of all,
we're going to do an overall kind of
big picture view of the urine,
the color, the appearance,
and the odor
Next we can look
at the pH level.
02:15
Remember the kidneys are very
involved in acid-base Balance.
02:18
So knowing the pH of the
urine will also help us,
Now that's not all as they
say in most infomercials
also tell us about
the presence of blood,
extra protein glucose,
ketones, bilirubin,
Um cells, crystals,
cast which are these weird kind
of protein shapes.
02:34
We'll talk about those later
bacteria or other germs.
02:39
Okay.
02:39
So (shoosh)
that others category
is really really big.
02:44
So I want to go back and
review the first three things
we talked about color,
appearance and odor, right?
Now we're getting a
little more detail
when we talk about pH level
and then all the other stuff that
could be present in the urine.
03:01
Each one of these
other categories
gives us an idea of what's
going on in the body.
03:07
The blood could be
a sign of infection
or there might be some
trauma to the urinary tract
increased protein
tells me that the
kidneys aren't doing well
and we watch that very
closely and diabetic patients
because diabetic patients
are at an increased
risk for kidney damage.
03:23
So we watch their protein
levels in their urine closely
as an indication of
their kidney function.
03:29
Glucose, Hey,
if their blood sugar's really high
we can end up with extra
glucose in the urine.
03:35
Ketones are something
that we look for
in a diabetic patient.
03:40
I'm sure you've heard of
diabetic ketoacidosis.
03:44
That's when a diabetic
client can't get their energy
in the form of glucose
out of their bloodstream
and into their cells.
03:51
So their body will go after
fat as a source of energy
and one of the waste products
of breaking down
the fat is ketones.
03:59
So, We usually see
this in a patient
who's not able to
get the glucose
into their bloodstream.
04:05
Now, there's some extreme diets
that can also cause
ketones in your urine,
but we're talking about someone
who's eating a typical American diet
not someone who's
on an extremely
low carb keto diet.
04:17
Now bilirubin also indications
and cells and crystals and casts
and we'll talk more
about those later.
04:22
But we just kind of put these
together in a category say
that's why a urinalysis
can tell us so much
about a patient.
04:29
I mean, Who knew you could
learn that much through pee.
04:33
I know you've often wondered.
04:35
Hmm.
04:36
What is urinary sediment?
Yeah, try that one at dinner
tonight with your family.
04:41
This will go over big.
04:43
Well, here's what it is.
04:44
They take the urine
and they centrifuge it.
04:46
So any of this sediments in the
urine are on the bottom of the tube
then they kind of pour off that
fluid on the top of the tube.
04:54
They shake it up again.
04:56
And then they look at this
They look at it
under the microscope.
04:59
They look at sediments, cells, crystals,
or other substances that might be there.
05:04
So this part of a urinalysis
looking at urinary sediment
is going to require
a microscope to look
for all these special types
of cells and other substances.
