00:00:05.138 --> 00:00:08.408
The sulfur salicylic acid test, or SSR

00:00:08.408 --> 00:00:12.078
test is done to confirm the presence
or absence of protein in the urine.

00:00:12.445 --> 00:00:16.850
Depending on the facility's protocol,
this test may be performed to confirm

00:00:16.850 --> 00:00:20.620
positive or negative protein results
from the initial screening test.

00:00:20.920 --> 00:00:25.158
This test semi quantitatively measures
the concentration of protein in the urine.

00:00:25.458 --> 00:00:29.162
Positive identification of a specimen
must be maintained through the complete

00:00:29.162 --> 00:00:30.597
testing process.

00:00:30.597 --> 00:00:34.267
Supplies needed for this test
include a test tube rack,

00:00:34.567 --> 00:00:38.505
clean dry test tubes, a bottle of 20% SSR,

00:00:39.005 --> 00:00:42.175
and an adjustable pipette with tips
to deliver one milliliter

00:00:42.842 --> 00:00:45.278
using a permanent marker label one test

00:00:45.278 --> 00:00:48.281
tube for each specimen tested.

00:00:49.616 --> 00:00:51.918
The specimen must be thoroughly mixed
by gently

00:00:51.918 --> 00:00:54.921
inverting the container
a minimum of eight times.

00:00:55.021 --> 00:00:57.757
Remove the cap from the specimen
container and place

00:00:57.757 --> 00:01:00.760
at specimen side up onto the benchtop.

00:01:00.960 --> 00:01:04.430
Add one milliliter of urine specimen
to a clean, dry test tube.

00:01:05.899 --> 00:01:08.401
Dispose
of the pipette tip into an appropriate

00:01:08.401 --> 00:01:10.870
bio hazardous waste receptacle.

00:01:10.870 --> 00:01:15.508
Recap the specimen using a new pipette tip
at approximately one

00:01:15.508 --> 00:01:19.913
milliliter of 20% SSR to the tube,
for a total volume of two milliliters.

00:01:20.346 --> 00:01:22.715
These measurements
do not have to be exact,

00:01:22.715 --> 00:01:24.817
but there should be equal volumes
of urine.

00:01:24.817 --> 00:01:28.621
An SSR dispose of the pipette tip
into a appropriate bio

00:01:28.621 --> 00:01:30.523
hazardous waste receptacle.

00:01:30.523 --> 00:01:34.494
Gently shake the tube or tubes
to completely mix the specimen

00:01:34.494 --> 00:01:36.162
and SSR solution.

00:01:36.162 --> 00:01:39.532
Using a dark background may be helpful
when grading the reaction.

00:01:40.199 --> 00:01:43.202
Grade the appearance of the solution
and report the results.

00:01:43.403 --> 00:01:46.539
Discard the test tube into a bio
hazardous waste receptacle.
