J. Mitra Scrub Typhus (Tsutsugamushi) IgM & IgG Card is a rapid, high-sensitivity diagnostic kit engineered for the qualitative detection and differentiation of IgM and IgG antibodies to Orientia tsutsugamushi in human serum, plasma, or whole blood. A critical asset during monsoon and post-monsoon fever outbreaks across India, this rapid test card is heavily relied upon by clinicians, epidemiologists, diagnostic laboratories, and hospital emergency wards. Because scrub typhus mimics other acute tropical fevers like dengue, malaria, and typhoid, this rapid card serves as a vital first-line triage tool to confirm or rule out mite-borne rickettsial infections swiftly.

Perfectly tailored for professional healthcare environments—especially in rural clinics and tier-2 or tier-3 medical centers where advanced laboratory infrastructure might be limited—this test card drastically accelerates clinical decision-making. Utilizing a highly sophisticated lateral flow immunochromatographic assay, the device features distinct, pre-coated regions that separately capture early-stage (IgM) and past/chronic (IgG) antibodies. Requiring just a tiny volume of patient sample, the J. Mitra card delivers clean, unambiguous visual bands on the test window, allowing healthcare professionals to initiate targeted antibiotic therapies quickly and avoid severe systemic complications.

Key Benefits:

Simultaneous Antibody Detection: Accurately differentiates between IgM (active/acute infection) and IgG (past exposure or chronic phase) antibodies on a single card.
Rapid Diagnostic Turnaround: Provides clear, easily readable visual lines within 15 to 20 minutes, allowing for immediate patient assessment and triage.
Excellent Clinical Performance: Highly evaluated for sensitivity and specificity against Indian strains of Orientia tsutsugamushi, ensuring reliable diagnostic support.
Versatile Sample Processing: Works efficiently with human whole blood, serum, or plasma, providing maximum flexibility for lab technicians.
Built-In Quality Control: Features a dedicated Control (C) line zone that indicates proper fluid migration, verifying the test's validity in real-time.

How to Use ( Scrub Typhus Tsutsugamushi IgM & IgG Card )

Step 1: Bring to Room Temperature: Allow the sealed foil pouch, patient sample, and assay buffer solution to reach room temperature before starting the procedure.
Step 2: Place the Device: Open the pouch, retrieve the test card, and place it flat on a clean, stable, and completely horizontal surface.
Step 3: Add the Patient Sample: Using the provided specimen dropper, carefully add the recommended microliter volume of serum, plasma, or whole blood into the designated sample well (S).
Step 4: Dispense the Buffer: Immediately add the specified number of drops of the assay buffer solution into the buffer well to facilitate sample flow across the membrane.
Step 5: Interpret the Results: Set a timer and read the visual bands between 15 and 20 minutes. Do not read or record any results after 20 minutes, as background color shifts may compromise accuracy.

Safety & Clinical Information:

Strictly for Professional Use: This kit is designed exclusively for in vitro diagnostic use by trained medical laboratory professionals and is not intended for home self-testing.
Preliminary Screening Only: A positive result indicates a strong presumption of scrub typhus. All rapid test results must be clinically correlated with patient symptoms and confirmed via secondary lab methods like ELISA or PCR if required.
Biohazard Precautions: Consider all blood samples and used test materials as potentially infectious. Dispose of cards, droppers, and lancets safely in designated biohazard sharp or medical waste bins.
Storage Protocols: Store the kits in their original sealed pouches between 2°C and 30°C. Protect the kits from freezing temperatures, boiling heat, and excessive ambient moisture.
