Who should get Walnut done in Kolkata?

Kolkata's June-to-October monsoon season brings sharp spikes in dengue, typhoid, malaria, and leptospirosis , particularly in flood-prone areas such as Behala, Dum Dum, Howrah, and Ultadanga. Early testing is essential because each condition requires a different treatment approach. Walnut is commonly included in a food allergy panel or specific IgE panel. Doctors may order it for people with hives, swelling, stomach pain, vomiting, or breathing difficulty after eating nuts. Adults above 30 in Kolkata benefit from periodic health screening that includes Walnut as part of a broader preventive panel. Residents of Alipore, Jadavpur, and across the city with chronic conditions, those on long-term medication, and individuals with a relevant family history should test at the frequency their specialist recommends.

What conditions can Walnut help diagnose?

The conditions diagnosable through Walnut depend on the specific markers the test measures. Results either confirm a suspected diagnosis, support a clinical suspicion requiring further investigation, or effectively exclude the condition the test was screening for.

What do Walnut results mean?

Positive antigen test (dengue NS1, malaria RDT, typhoid Vi antigen): active infection , treatment should begin promptly. Positive antibody IgM: recent or active infection. Positive IgG without IgM: past infection or immunity, not active disease. Widal titre of 1:160 or above for Salmonella typhi H and O antigens supports typhoid diagnosis in a symptomatic patient with no prior typhoid history.

How often should Walnut be repeated?

For preventive screening with a normal baseline: annually for most adults above 35. For monitoring a known condition: at the interval your specialist recommends , typically every 3 to 6 months for active conditions and annually for stable, well-controlled ones.
