If you’re in Pune and suspect Chikungunya, you can get a diagnostic test to confirm the infection. In this test, a blood sample is collected (typically serum or plasma) and can be tested via two main methods. The first method is a molecular test (such as RT-PCR) to detect the viral RNA, which is most reliable when the sample is taken in the first few days (up to about 7 days) of symptom onset.The second method is a serologic (antibody) test, usually detecting IgM and sometimes IgG antibodies; this becomes useful after the first week of illness. No special fasting is generally required for the test, although some labs ask for light preparation. It’s advisable to consult with your healthcare provider about the appropriate test type based on how long you’ve been symptomatic.
