METHODS OVERVIEW

2 OF 2

2.1 Introduction

The CLINITEK® Status instrument is a reﬂectance photometer, which reads the changes in color of the Bayer urine reagent strips and immunoassay cassettes. A series of six light emitting diodes (LED) each at a different wavelength illuminates the entire strip or cassette length. Reﬂected light from the strip is then passed through a lens and focused on a photodiode detector array (CCD) which then converts the light energy into an electronic signal. This signal is then passed through an A/D converter and then onto a microprocessor. Once there, the signal is processed into percent reﬂectances and then decodes. These decode values are compared to lookup tables containing speciﬁc decode ranges for each reagent and their respective clinical values. Results are reported to the customer via the touch screen, onboard printer, and/or through a computer interface.

For methods used on the urine reagent strips and immunoassay cassettes, refer to their speciﬁc product inserts.

4.2 Urinalysis Strip Test

A Full Strip Test allows you the option to enter an Operator ID, Patient Name and/or Patient ID prior to inserting a strip. The procedures to enter the Operator and Patient data are presented in this section. The strip testing process is identical to a Quick Strip Test.

Testing is started from the main Select screen.

Touch Strip Test to conduct a Bayer urinalysis strip test.

The next screen that appears is Operator ID.

OPERATIONS / PROCEDURES

There are two options under Operator ID: Last Operator or Enter New Operator ID.
