Summary:
The article from “The Hindu” discusses the limitations of relying solely on numerical values, like BMI or lab results, to determine a person’s health. It highlights how these “reference ranges” are statistical constructs, influenced by factors like ethnicity, gender, age, and even the specific testing methods used. The author argues that diagnostic cut-offs are often arbitrary compromises, balancing sensitivity and specificity, and must be interpreted within the context of a patient’s individual circumstances and clinical picture. It stresses the need for more population-specific reference ranges, particularly in India, to avoid over- or under-diagnosing diseases. Ultimately, the article advocates for a more holistic approach to healthcare, where numbers are just one piece of the puzzle, alongside a thorough patient history and clinical examination.

Health Numbers Aren’t Gospel: Experts Urge Contextualized Approach to Diagnosis
NEW DELHI, November 19, 2025 – Are you truly healthy if your lab results fall within the “normal” range? According to Dr. C. Aravinda, writing in today’s edition of The Hindu, the answer is more complex than a simple number. The article challenges the widespread reliance on universal cut-offs for health markers like BMI and blood glucose, arguing that they are often statistical constructs with limitations.
“The line between health and disease isn’t a sharp one; it’s more like a gradual shift,” Dr. Aravinda explained. The piece emphasized that factors such as ethnicity, age, gender, and even the laboratory where the test is processed can impact what is considered “normal.”
The article cites the example of Dwayne “The Rock” Johnson, whose BMI would classify him as “obese” despite his obvious physical fitness. It also points out that Asian populations tend to develop diabetes at lower BMI levels, necessitating a revision of WHO guidelines.
The core message is that reference ranges are not absolute truths but rather statistical guidelines. Falling outside the range doesn’t automatically mean illness, nor does staying within it guarantee good health.
“We need to bring the number back into the world of the patient,” Dr. Aravinda writes, urging healthcare professionals to correlate lab results with a patient’s full clinical picture.
The article also calls for more extensive, India-specific reference studies to avoid over- and under-diagnosing diseases based on Western benchmarks. It suggests that healthcare interpretation in India should recognise the differences rather than borrow the benchmarks from the West. “Ultimately, health workers must focus as much on the term ‘range’ as on ‘reference’,” the piece concludes.
