Platinum Urine Chemistry Test System
Quick Start Guide
PERFORMING A URINALYSIS TEST
-
Have a urine sample, a Clarity Diagnostics urine reagent test strip, paper towel, and the analyzer turned on and ready for use. The use of urine preservatives is not recommended. If testing cannot be done within an hour after collection, refrigerate the specimen immediately and let it return to room temperature before testing.
Biohazard: Wear personal protective equipment when handling the patient specimen and performing the test.
Use universal precautions for any biohazard materials. -
Turn on the device. Select Test Strip from the main menu.
-
Scan or enter the barcode from the urine reagent strip bottle and press Enter.
-
Scan or type in the patient ID and press Enter, or press Enter to skip entirely.
-
Follow the instructions listed on the display screen. Dip the strip into the urine sample one time, and remove it immediately. Ensure that all the pads on the strip are saturated with the urine sample. Dipping should not exceed 10 seconds. Then, press Start.
-
After pressing the Start button, the analyzer begins 10 seconds of selfcalibration. You will have 10 seconds to complete steps 7 and 8.
-
Touch the long edge of the strip onto a paper towel to remove the excess urine.
-
Place the strip on the strip bed with the test pads facing up. Ensure that the test strip is inserted fully into the back of the strip bed.
-
When calibration is completed, the analyzer retracts the strip bed with the strip, and it will begin analysis. A timer on screen will count down the time remaining in the strip analysis process.
-
The test result will be displayed on screen and printed. Select Results to go to the result menu. Select Next Test to perform the next test.
CLIA WAIVER INFORMATION
This Quick Start Guide is for use with the CLIA Waived Clarity Platinum Urine
Chemistry Test System. This test is waived under CLIA ’88 regulations. This
test is only waived for urine specimens. Failure to adhere to the instructions
for use will result in the test being considered high complexity and subject
to all CLIA requirements. A CLIA Certificate of Waiver is required to perform
this testing. A Certificate of Waiver can be obtained from the Centers for
Medicare & Medicaid Services (CMS). Visit
www.cms.gov to obtain an application (Form CMS-116).
You must follow the manufacturer’s instructions to perform tests. You should
read the complete test procedure before performing the test.
Cleaning and Maintenance
For daily cleaning:
Wet a cotton tipped swab with warm water and carefully clean the strip bed.
Dry the strip bed with a clean cotton swab.
For weekly maintenance:
- Select the Advanced option from the main menu. Select Strip Bed Maintenance and press the top arrow ⇓ to unload the strip bed and remove it for cleaning.
- Clean the strip bed with a 70% alcohol solution. Avoid wiping the white color block on the top right side of the strip bed and avoid cleaning the groves on the left side of the strip bed. Dry the strip bed completely with a lint free tissue or clean cotton swab.
- Return the strip bed into the device by seating it back into the groove until you feel pressure and it stays in the machine by itself. Press the bottom arrow ⇑ on the screen and the strip bed will be retracted.
- Press ◀ icon to go back to the main menu.
- Before proceeding with patient sample testing, please perform a Quality Control test as described below.
STORAGE AND RECOMMENDED HANDLING PROCEDURES
- For the best performance, ensure the analyzer is operated between the temperatures of 59-86°F (15-30°C) and relative humidity of 18-80%.
- Store test strips at room temperature between 59-86°F (15-30°C), a relative humidity of 20%, and out of direct sunlight. Do not use strips after their printed expiration date. Opened bottles of test strips are stable and should be used within 3 months when stored at optimal conditions.
Quality Control
-
On the main menu, select Advanced.
-
On the advanced setting screen, select Quality Control.
-
Select Perform QC Test.
-
Scan or enter the barcode from the urine reagent strip bottle.
-
Scan or enter the barcode from Clarity’s Urine Control Level I Bottle.
-
Follow the instructions on the screen for performing QC with Level I Control. Dip the reagent strip in Level I Control, or place one drop of Control on each reagent pad and press the Start button.
-
The analyzer will perform auto-calibration. You will have 10 seconds to prepare the test. Touch the long edge of the strip onto a paper towel to remove the excess Quality Control sample.
-
Place the strip on the strip bed with the test pads facing up. Ensure that the test strip is fully inserted into the back of the strip bed.
-
A timer on the screen counts down the time remaining in the strip analysis process.
STORAGE AND STABILITY FOR URINE CONTROLS:
The urinalysis controls should be stored at 35–46°F (2-8°C) when not in use. Do not freeze. When stored at 35–46°F the controls are stable until the expiration date stated on the label. When stored at room temperature (64–77°F), the controls are stable for 7 days or until the expiration date stated on the label.
-
The QC Level I test results will display on the screen and print automatically, depending on your printer settings. If QC Level I fails, you will be prompted to repeat the test. Once QC Level I passes, press Next Test to run a QC test with Control Level II solution.
-
Scan or enter the barcode from Clarity’s Urine Control Level II Bottle.
-
Follow the instructions on the screen for performing QC with Level II Control. Dip the reagent strip in Level II control, or place one drop of control on each reagent pad and press the Start button.
-
The analyzer will perform auto-calibration. You will have 10 seconds to prepare the test. Touch the long edge of the strip onto a paper towel to remove the excess quality control sample.
-
Place the strip on the strip bed with the test pads facing up. Ensure that the test strip is fully inserted into the back of the strip bed.
-
The QC Level II test results will display on the screen and print automatically, depending on your printer settings. If QC Level II fails, you will be prompted to repeat the test. Once QC Level II passes, press ◀ to return to the main menu.
Significance of QC tests and Consequences of Not Performing QC Procedures
Quality control testing is a process of detecting errors within the testing
site to ensure both the reliability and accuracy of test results in order to
provide the best possible patient care. Therefore, to ensure the accuracy and
performance of the Clarity Platinum Test System, quality control procedures
are incorporated into the Clarity Platinum analyzer. The purpose of including
quality control procedures is to evaluate the reliability of the test system
by assaying stable quality control material that resembles patient samples.
The quality control function is designed to detect, reduce, and correct
deficiencies in a laboratory’s internal process prior to the release of
patient results. Failure to conduct quality control testing or carry out QC
procedures could lead to unreliable performance of the test system, which
could result in misdiagnosis, delayed treatment, and increased costs due to
retesting. It is of great importance to ensure all results are both accurate
and reliable.
Clarity Diagnostics produces Quality Control Solution Levels I and II, which
are used to perform quality control testing. For CLIA Waived settings, Clarity
Urinalysis quality controls must be tested under the following conditions:
When a new canister of strips is opened OR
100 tests have been performed OR
Test results appear to be inaccurate OR
A
new operator uses the analyzer OR
Each new day of testing OR
30 days have passed since the previous QC Pass OR
After performing maintenance or service on the analyzer.
If the QC tests do not provide the expected results, perform the following
checks:
Ensure the strips used are not past their expiration date.
Ensure the strips are fresh from a new canister.
Ensure the controls are not past their expiration date.
Repeat the test to ensure no errors were made during the test.
If QC testing still does not provide the expected results, call Clarity
Diagnostics Technical Support:
877-485-7877, MondayFriday, 8am-6pm
EST.
Once the QC test is successfully performed, the analyzer will display the
results on the screen. A QC pass message will enable the user to proceed to
patient sample testing. A QC fail message will cause a system lockout, and the
user cannot perform any patient testing until the quality control test is
completed successfully. If the problem persists, stop the test and call
Clarity Diagnostics technical support at
877-485-7877, Monday – Friday 8am to
6pm EST, or email us at
techsupport@claritydiagnostics.com.
