Methodology

RRMC and TRMC: Automated testing using the iRICELL 2000 system.

 

Macroscopic testing is performed using test strips which are read by a dual wavelength reflectance system, specific gravity is determined by measuring the refractive index. Color is measured by transmitted light and clarity is measured by scattered light.

 

Microscopic testing is performed using an automated particle imaging system with manual review when indicated.

 

AACH: Automated by dipstick reader and manual microscopic.
