Jaipur Doctor's Quiz Diagnoses Lung Disease at 90% Accuracy

Breathing problems affect millions across South Asia, but one lung disease has been nearly impossible to diagnose until now.

Dr. Sheetu Singh, a pulmonologist in Jaipur, India, has created a breakthrough tool that identifies Hypersensitivity Pneumonitis with over 90% accuracy. The condition causes permanent lung scarring and has historically been one of the hardest respiratory diseases to detect.

The challenge has always been that HP looks like almost every other breathing problem. Patients experience persistent cough, breathlessness, fatigue, and weight loss, symptoms shared by dozens of lung conditions. This confusion has led to delayed treatment and worsening disease for countless patients.

Dr. Singh's solution is surprisingly straightforward: a questionnaire. The HP-SAQE (South Asian Questionnaire for Environmental Exposure) asks patients about their daily surroundings, focusing on exposure to birds, dust, and damp conditions that trigger the disease.

The tool is specifically designed for South Asian countries like India, Pakistan, Sri Lanka, and Bhutan, where HP is particularly common. By focusing on regional environmental factors, the questionnaire captures exposure patterns unique to these areas that generic diagnostic tools miss.

Patients who score nine or above on the questionnaire have a high likelihood of HP. This quick assessment allows doctors to catch the disease early, when treatment can prevent permanent lung damage. The timing matters because once lung tissue scars, the damage cannot be reversed.

The international medical journal Thorax published Dr. Singh's research, giving the tool credibility in the global medical community. Thorax is one of the most respected respiratory medicine journals worldwide, and publication there signals that this innovation meets rigorous scientific standards.

The Ripple Effect

The HP-SAQE could transform respiratory care across an entire region. South Asia is home to nearly two billion people, many living in environments with high exposure to HP triggers like agricultural dust and bird droppings.

Early diagnosis means patients can modify their environments and begin treatment before irreversible damage occurs. For rural communities with limited access to expensive diagnostic equipment, a simple questionnaire offers hope where advanced testing isn't available.

The tool also frees up medical resources. Doctors can screen patients quickly without costly imaging or invasive procedures, saving those resources for patients who truly need them.

This breakthrough shows how region-specific medical tools can outperform one-size-fits-all approaches. By understanding local environmental factors, Dr. Singh created something more accurate than generic international diagnostic criteria.

Thousands of South Asian patients can now receive accurate diagnoses and life-changing treatment thanks to one doctor's innovative thinking.
