CROMATEST ASLO/ASO LATEX ( SEROLOGY ANTIGEN) ONLY VIAL

CROMATEST ASLO/ASO LATEX ( SEROLOGY ANTIGEN) ONLY VIAL Overview

The CROMATEST ASLO/ASO LATEX is a high-precision serology reagent kit designed for the rapid detection and semi-quantitation of clinically significant levels of anti-streptolysin O (ASLO) antibodies in human serum. Utilizing a slide agglutination method, this kit is essential for diagnosing past or recent Group A streptococcal infections, such as rheumatic fever and glomerulonephritis. This listing is for the ASLO-Latex Antigen ONLY VIAL, ideal for laboratories in Bangladesh that require reliable reagents for routine biochemical analysis.

CROMATEST ASLO/ASO LATEX ( SEROLOGY ANTIGEN) ONLY VIAL Key Features

• Rapid Slide Agglutination: Provides visible results within 2 minutes using a mechanical rotator, ensuring fast turnaround times for patient diagnosis.
• High Diagnostic Accuracy: Features a diagnostic specificity of 97% with an analytical sensitivity of approximately 200 IU/mL (± 50 IU/mL).
• Semi-Quantitative Capability: Allows for the determination of ASLO titers to monitor the progression of streptococcal infections over time.
• No Prozone Effect: Reliable results up to 1500 IU/mL without the interference of the prozone phenomenon.
• Interference Resistant: Formulated to resist interference from common substances like hemoglobin (<10 g/L), bilirubin (<20 mg/dL), and lipemia (<10 g/L).
• Ready-to-Use Reagents: The antigen suspension is prepared for immediate use, streamlining the laboratory workflow.

Technical Specifications

• Principle: Slide agglutination test using polystyrene latex particles coated with stabilized streptolysin O antigen.
• Storage Conditions: Must be stored at 2-8°C. Do not freeze, as freezing alters the functionality of the reagent.
• Reagent Composition: Contains polystyrene latex particles in buffered saline solution with 0.95 g/L of sodium azide (preservative).
• Sensitivity: Minimum detectable unit (analytical sensitivity) is approximately 200 IU/mL.
• Sample Requirement: Fresh, clear human serum. Stable for up to one week at 2-8°C or longer at -20°C.
• Safety Precautions: Contains sodium azide. Handle with caution; avoid contact with skin or mucous membranes. Components are tested to be negative for anti-HIV 1+2, anti-HCV, and HBsAg, but should be treated as potentially infectious.
