Latex agglutination tests for Rheumatoid Factor (RA), C-Reactive Protein (CRP), and Anti-Streptolysin O (ASO) are used to diagnose and monitor various conditions, primarily autoimmune and infectious diseases. These tests involve mixing a patient's serum with latex particles coated with specific antibodies, and observing for agglutination (clumping), which indicates a positive result.

The Arkray RPR (Rapid Plasma Reagin) test kit is a carbon antigen-based flocculation test used to detect syphilitic reagin antibodies in serum or plasma. It's a rapid test, providing results within 8 minutes, and utilizes stable, aqueous, ready-to-use reagents, eliminating the need for serum/plasma inactivation. The kit is manufactured by Arkray, and is CE certified. 

Arkray Tuberculin PPD, also known as Purified Protein Derivative, is a substance used in the Mantoux test to detect tuberculosis infection. It's a standardized solution injected intradermally to assess for sensitization to Mycobacterium tuberculosis. The Mantoux test, or tuberculin skin test (TST), involves injecting a small amount of Tuberculin PPD into the skin, and the resulting skin reaction (induration) is measured to determine if a person has been exposed to TB bacteria.

Brucella Suspension, specifically for B. abortus and B. melitensis, is used in diagnostic tests, like agglutination tests, to detect and identify antibodies against these bacteria in serum samples. ARKRAY is a manufacturer of these stained Brucella suspensions. These suspensions are used in both slide and tube agglutination tests

The ARKRAY Widal Antigen Set is a diagnostic kit used to detect Salmonella infections, specifically typhoid and paratyphoid fevers. It contains antigens prepared from smooth, non-fimbriate Salmonella strains. The kit is available in different antigen sets and is designed for both slide and tube tests, with a long shelf life of 18 months. 

Stained Salmonella Antigen for Slide & Tube Tests Antigens are prepared from specially selected smooth, nonfimbriate strains.

Spanclone is a Monoclonal Agglutination Sera for the Determination of Human Blood groups (ABO).
