Hi!
Welcome to our video series
on interpreting lab values.
00:05
In this one.
We're kind of get a little personal
because we're talking about
a clean catch urine sample.
00:12
Now this isn't a
real glamorous test,
but it is an important one
and one that you do very
commonly in your practice.
00:18
So, what's the goal?
What is a clean catch?
Well, the target is
which is why I have an arrow
there for you on the screen
as you want to prevent
the bacteria from the skin
of the penis or the vagina from
contaminating the urine specimen.
00:33
That's why it's
called a clean catch.
00:36
Okay, so I don't want the external
bacteria to contaminate the sample
because I'm looking for
the internal bacteria
that's what I want to treat.
00:46
I don't want to treat
the external bacteria.
00:49
So you're going to have
to instruct the patient
on how they can clean themselves
because we want to make sure they
minimize the bacteria from the skin
around the urinary opening from
contaminating the urine specimen.
01:01
This is where it
gets really personal.
01:04
Now you can instruct the patient
on how to do this for themselves.
01:07
You've probably done this
in the physician's office.
01:10
Male patients who
are not circumcised
will need to
retract the foreskin
before cleaning the
head of the penis.
01:16
Female patients will need to
clean around the urinary meatus
by holding the labia apart
and wiping from front to back
with a separate towellete on the
right, the left,
and then in the middle.
01:29
Think about when you're
being a female patient
we do the same things with
the swaps right, left,
and then the middle,
you want to instruct them to do
the same thing with the wipes.
01:40
Now here's where clean catcher
and gets a little tricky
and usually a little messy.
01:46
I've got three toilets there
for you to help you
understand this concept
because the patient is going
to need to start to urinate,
stop the urinary stream
and restart the stream after
placing the specimen cup
to collect a sample.
02:01
Yeah, I got a million
stories about this
but none of that is appropriate.
02:06
So let's just focus on getting
the target the job done.
02:10
You've instructed the patient
on how to clean
themselves to make sure
that external bacteria
doesn't get into the sample.
02:17
Now, they're going to need
to start their stream,
stop it then get
the cup in position
to collect the sample
and restart their stream.
02:25
Now it's actually a lot easier for
men than it is for females to do this.
02:30
Men have a lot more
directional stream
women kind of have a sprinkler.
02:34
So just let them know
you've got towels in there
for them to clean up afterwards
because unless you're
really proficient at this
this can be a little messy.
02:43
So start the stream, stop it,
put the cup in,
collect the sample.
02:49
That's what a clean
catch urine sample is.
02:52
Now they're gonna have
to label the specimen.
02:54
Usually before you give
them the specimen cup
you want to put the label on it,
so you've got the right
patient identification
information on the cup.
03:02
Now if you've done this
at the doctor's office
usually go into a
private bathroom,
you collect the specimen
and then they have
a special place
for you to put the cup.
03:11
If you're in the
hospital setting,
you'll be involved in making
sure this is properly labeled
and makes it down to
the lab for testing.
03:18
Now labels can be
filled out by hand
or usually we use
pre-printed labels.
03:23
But either way works fine,
as long as the specimen
is labeled with the date
and the time of the collection
along with the patient's name.
