00:00
So protein in your urine,
which is much easier to
say than albuminuria.
00:05
It's a sign of kidney disease.
00:07
Hope that's solid
in your brain now
so we can do a dipstick
that isn't that a funny word
because dipstick is usually
not a term of endearment.
00:16
But here we're actually
talking about a strip
that has chemicals on it
and you dip it in urine.
00:24
That's what a dipstick is when
we're talking about it here.
00:27
So you see our bottle
you see those strips,
you see a urine sample
in the background,
actually looking pretty nice
are right there fairly hydrated.
00:35
It looks like it's pretty clear.
00:37
Nice color yellow.
00:38
We're good to go.
00:40
Everything looks fine but
then you put that dipstick in,
you dry it off,
and you read it.
00:46
What do you think a
two plus urine means
on a standard dipstick?
Okay that lets us know we've got
protein positive in the urine.
01:00
Now you can see on the
bottle, there you have a label
and you've got the different
colors as they go along
you hold the strip
up to the bottle
and you compare which color is
closest to the key on the bottle
and that will give
you the reading.
01:14
Now this is can
be done anywhere,
obviously because it's all
you can do it at home even
with a dipstick and a bottle
but most often in
a clinical setting
they will do a dipstick but
they'll read it with a machine.
01:25
Okay so now you know what 2+ urine
means on a standard urine dipstick
that means they've got protein
present in their urine.
01:33
Okay so now we've established
what a urine dipstick is.
01:37
It's just hard for
me to say that word
and keep a straight face because
like I said in my circle of friends
dipstick is not a
term of endearment,
but let's be serious.
01:48
We're talking about the
clinical application here.
01:51
So a urine dipstick
is very specific
for albumin or protein
but it's not extremely sensitive
to low levels of albumin.
02:01
Now next to your notes right
there to low levels of albumin,
I want you to write
the word micro,
M-I-C-R-O.
02:10
That means tiny.
02:12
So if you have microalbuminuria,
I mean, you've got really small
amounts of protein in your urine
more than we probably
want you have,
because protein should
stay in your blood
but it's not enough to be
picked up by the dipstick.
02:30
See the protein in your urine
has to be about 10 to 20
before it'll be
detectable by a dipstick.
02:36
So dipstick grading
goes from - to 4+
it's impacted by
urine concentration.
02:43
So if that urine is
highly concentrated
means one first of
all, my nose goes
it's probably a really stinky,
because you have less
water, right?
The patient is dehydrated,
they put out a sample
that is darker,
you know that it's
highly concentrated.
03:01
So that could also
throw off the reading.
03:04
This is just a great test to use
but not as amazing as a 24-hour
urine collection for protein.
03:11
So why don't we just do
a 24-hour collection?
Well, I think you know
the answer to that
if you've watched the
rest of our video series.
03:18
So way more complicated
and cumbersome
to do a 24-hour
urine collection.
03:23
You got to
keep it refrigerated
versus this urine
dipstick for protein,
you get a sample
you dip the stick.
03:29
We're good to go.
03:30
It's much easier and faster.
03:32
It's just not as specific,
if this comes back positive
and the doctor wants a follow-up
and we may order a
24-hour urine collection
so we can have a really accurate description
of their protein in their urine.
