With chikungunya outbreaks rising across regions, the demand for precise lab-based diagnostic solutions is more critical than ever, according to Dr. Sameer Bhati, Director of Star Imaging and Path Lab Pvt. Ltd. Early and accurate detection, he says, is the first step toward controlling the spread and preventing complications.

Key Highlights

RT-PCR remains the gold standard

• RT-PCR is the most reliable method for detecting chikungunya in the first week of infection, when the virus is still present in the blood.

• Dr. Bhati says, “It provides a definitive diagnosis, helping both patients and doctors take timely action.”

Antibody tests help identify past infections

• IgM antibody tests detect recent infections (positive within 7–10 days).

• IgG tests reveal past infections and immunity.

• These tests are crucial to track disease spread and immunity levels in communities.

Rapid tests are helpful, but less reliable

• Rapid Diagnostic Tests (RDTs) offer quick results but lack the accuracy of RT-PCR.

• Dr. Bhati warns, “RDTs are useful for screening, but confirmatory lab testing is always recommended.”

Testing timing is critical for accuracy

• RT-PCR: Best during the first 7 days of symptom onset.

• IgM tests: Effective after the first week.

• IgG tests: Useful for long-term immunity assessment.

Dr. Bhati urges healthcare providers to invest in lab-based diagnostics over rapid tests, especially during outbreak situations. He emphasizes that RT-PCR and antibody tests reduce misdiagnosis, aid in public health planning, and help authorities manage outbreaks better. With chikungunya symptoms often overlapping with dengue and Zika, accurate diagnosis is essential to prevent complications and save lives.
