HAV Rapid Test Device (WB/S/P)

Hepatitis A Virus, also called HAV, is a virus that affects the liver. It usually spreads through contaminated food, water, or close contact with an infected person. Hepatitis A is different from Hepatitis B and Hepatitis C because it usually causes acute infection and does not commonly become a chronic lifelong infection.

• The HAV Rapid Test Device is useful when quick screening is needed in professional healthcare settings.
• Hepatitis A outbreaks may occur through contaminated food or water, poor sanitation, travel exposure, or close-contact transmission.
• Rapid testing helps support early clinical evaluation and public health response.
• IgG and IgM differentiation helps healthcare professionals understand the possible stage of immune response.

The HAV Rapid Test Device by LARKSOIS Pharma may be used in professional diagnostic, public health, and healthcare screening environments.

Applications

• Hepatitis A antibody screening
• Differentiation of HAV IgG and IgM
• Acute infection evaluation support
• Travel and outbreak screening programs
• Clinic and laboratory workflow improvement
• Public health surveillance support
• Point-of-care infectious disease testing
• International diagnostic supply requirements
• Hospital and diagnostic laboratory testing

• The HAV Rapid Test Device works on a lateral flow chromatographic immunoassay principle.
• When whole blood, serum, or plasma is applied to the test device, the specimen moves across the membrane.
• If HAV IgG or IgM antibodies are present, they bind with specific test components and create visible colored lines.
• The control line confirms valid sample flow and proper test performance.

The HAV Rapid Test Device uses rapid lateral flow immunochromatographic technology for qualitative detection and differentiation of HAV IgG and IgM antibodies from whole blood, serum, or plasma specimens.

Benefits

• Qualitative detection of HAV IgG antibodies
• Qualitative detection of HAV IgM antibodies
• Differentiates IgG and IgM antibody patterns
• Suitable for whole blood, serum, or plasma specimens
• Simple visual result interpretation
• No major laboratory equipment required
• Supports hepatitis A screening workflows
• Useful for public health and outbreak screening programs

The HAV Rapid Test Device is designed for whole blood, serum, or plasma specimens. Correct specimen collection and handling are important for reliable test performance.

Guidance

• Use approved whole blood, serum, or plasma specimens only
• Collect specimens according to the product insert
• Use clean and suitable sample collection materials
• Avoid contaminated or improperly stored samples
• Add whole blood, serum, or plasma to the sample well
• Add buffer as instructed
• Read IgG, IgM, and control lines within the valid time window
• Handle all blood specimens as potentially infectious material

Note

Specimen collection, handling, testing, timing, and storage should always follow the official LARKSOIS Pharma kit insert.

The HAV Rapid Test Device by LARKSOIS Pharma is designed to detect and differentiate HAV IgG and IgM antibodies in whole blood, serum, or plasma specimens. HAV IgM may suggest recent or acute infection, while HAV IgG may suggest past exposure or immunity.

• HAV IgM may suggest recent or acute Hepatitis A Virus infection.
• HAV IgG may suggest past exposure, previous infection, or immunity.
• IgG and IgM differentiation helps healthcare professionals understand the possible stage of immune response.
• The test supports hepatitis A antibody screening, travel screening, outbreak support, and point-of-care infectious disease testing.

The HAV Rapid Test Device is a screening aid. It should not be used as the only basis for diagnosis, treatment, or public health decisions. Results should be interpreted with symptoms, exposure history, vaccination history, and other laboratory findings.

Instructions

• For professional in-vitro diagnostic use only
• Handle all blood specimens as potentially infectious
• Wear gloves during sample handling
• Do not reuse the test device
• Avoid cross-contamination
• Do not use damaged or expired kits
• Read results only within the recommended time
• Confirm results where clinically required

Instructions

• Rapid hepatitis A antibody screening
• Qualitative detection of HAV IgG antibodies
• Qualitative detection of HAV IgM antibodies
• Differentiates HAV IgG and IgM response patterns
• Suitable for whole blood, serum, or plasma specimens
• Simple visual result interpretation
• Supports travel and outbreak screening programs
• Useful for hospitals, clinics, and laboratories

Note

The HAV Rapid Test Device by LARKSOIS Pharma is developed for professional users who need practical and accessible hepatitis A screening support.

Steps

• Bring the test device, sample, and buffer to room temperature
• Open the sealed pouch only when ready to test
• Place the test device on a clean, flat surface
• Add whole blood, serum, or plasma to the sample well
• Add buffer as instructed in the kit insert
• Wait for the recommended reaction time
• Read IgG, IgM, and control lines within the valid time window
• Do not interpret results after the recommended reading time
• Dispose of used materials according to laboratory safety rules

Note

Testing should be performed by trained healthcare professionals according to the official LARKSOIS Pharma product insert.

Positive

IgM positive / IgG negative may suggest recent or acute HAV infection. IgG positive / IgM negative may suggest past exposure, previous infection, or immunity. IgG positive / IgM positive may suggest recent infection, recovering phase, or active immune response.

Negative

IgG negative / IgM negative means no detectable HAV IgG or IgM antibodies were found. If symptoms continue, further testing may be recommended.

Invalid

If the control line does not appear, the test is invalid and should be repeated with a new device according to the product insert.

Instructions

• Store the HAV Rapid Test Device according to the product label and insert
• Store in a dry place
• Keep sealed until use
• Do not freeze
• Avoid heat and direct sunlight
• Protect from moisture
• Do not use expired kits
• Use immediately after opening the pouch

Instructions

• For professional in-vitro diagnostic use only
• Handle all blood specimens as potentially infectious
• Wear gloves during sample handling
• Do not reuse the test device
• Avoid cross-contamination
• Do not use damaged or expired kits
• Read results only within the recommended time
• Confirm results where clinically required
