Spirometry is a lung function test that measures how much air you can inhale and exhale, and how quickly you can do it.

Wear loose clothing, avoid heavy meals or intense exercise before the test, and follow any specific instructions from your doctor.

No, spirometry is non-invasive and painless. You will be asked to breathe into a device, which may feel slightly uncomfortable but is not painful.

The test itself takes about 15-30 minutes. Results are usually available immediately or within a few hours.

The frequency depends on your health conditions and doctor’s recommendations. It may be performed regularly for ongoing monitoring or as needed for diagnosis.

A positive result indicates past infection with the Dengue virus or successful vaccination against Dengue.

No, additional tests, such as Dengue IgM or PCR, may be required to differentiate recent infections from past ones.

No, the Dengue IgG test is not suitable for diagnosing acute Dengue infection. IgG antibodies appear later in the course of infection.

Dengue IgG antibodies can remain detectable in the bloodstream for months to years after infection or vaccination.

A negative result suggests no detectable Dengue IgG antibodies. If symptoms persist or there is a recent exposure, consult a healthcare provider for further evaluation.
