00:00:05.105 --> 00:00:08.441
Performance of the acid test is done
to confirm the initial positive

00:00:08.441 --> 00:00:12.379
ketone results from the reagent dipstick,
and to semi quantitatively

00:00:12.379 --> 00:00:15.382
measure the concentration of ketone bodies
in the urine.

00:00:15.548 --> 00:00:18.818
The performance of the acid test
will be demonstrated using positive

00:00:18.818 --> 00:00:20.720
and negative control specimens.

00:00:20.720 --> 00:00:23.790
Positive identification of a specimen
must be maintained

00:00:23.790 --> 00:00:26.793
throughout the complete testing process.

00:00:26.793 --> 00:00:30.330
Supplies needed to perform
this test include paper towels,

00:00:30.797 --> 00:00:35.034
a permanent marker, tweezers, disposable
pipettes,

00:00:35.535 --> 00:00:40.607
a timer, a bottle of acid test tablets,
and the manufacturer's color chart.

00:00:41.241 --> 00:00:45.712
The test is performed on a clean, dry
paper towel using a permanent marker

00:00:45.712 --> 00:00:46.179
label.

00:00:46.179 --> 00:00:49.249
The area of the paper towel
you will use for each specimen

00:00:49.749 --> 00:00:52.452
using clean, dry tweezers, remove one

00:00:52.452 --> 00:00:55.455
acid test
tablet per specimen from the bottle

00:00:55.622 --> 00:00:58.625
and place it onto the paper towel
in the labeled areas.

00:00:58.892 --> 00:01:02.495
Acid test tablets are sensitive
to light, heat, and moisture,

00:01:02.795 --> 00:01:05.498
so the bottle needs to be recapped
immediately

00:01:05.498 --> 00:01:08.468
after removing a tablet
and when not in use.

00:01:08.568 --> 00:01:12.472
Also, do not touch the tablets
with anything but the tweezers.

00:01:12.939 --> 00:01:15.608
The specimen must be thoroughly mixed
by gently

00:01:15.608 --> 00:01:18.578
inverting the container
a minimum of eight times.

00:01:18.611 --> 00:01:22.248
Carefully remove the cap from the specimen
container and place it

00:01:22.248 --> 00:01:26.919
specimen side up onto the benchtop
using a disposable pipette.

00:01:27.186 --> 00:01:30.823
Gently dispense one drop of the urine
specimen onto the tablet,

00:01:30.823 --> 00:01:34.394
and then dispose of the pipette
into a bio hazardous waste receptacle.

00:01:34.894 --> 00:01:37.630
Immediately start a timer for 30s.

00:01:37.630 --> 00:01:40.566
Recap the specimen at 30s.

00:01:40.566 --> 00:01:41.968
Compare the color of the tablet

00:01:41.968 --> 00:01:46.005
against the manufacturer's color chart
and record the results as negative.

00:01:46.005 --> 00:01:48.841
Small, moderate, or large.

00:01:48.841 --> 00:01:52.779
Discard the paper towel and tablet
into a bio hazardous waste receptacle.
