Vertigo Evaluation Test (VNG, CCG, DVA, SVV, Caloric Testing)

I’m not sure what you mean by "CCG test" for vertigo. Do you mean a caloric test, VNG/ENG, cVEMP, or something else? Tell me which one you mean and I’ll provide a 50–75 word explanation.

Videonystagmography (VNG) is a noninvasive test for vertigo that records eye movements to evaluate the vestibular (inner ear) and central balance systems. Patients wear infrared goggles while following visual targets, changing head positions and undergoing caloric testing (warm/cool ear irrigation). VNG identifies abnormal nystagmus patterns to diagnose causes like peripheral vestibular loss, BPPV, or central disorders. It may cause brief dizziness.

A caloric test evaluates inner ear (vestibular) function by irrigating each ear canal with warm or cool water or air to stimulate the horizontal semicircular canal and trigger eye movements (nystagmus). With the patient reclined and head angled, clinicians record eye responses to compare left and right sides. Reduced or asymmetrical responses indicate vestibular weakness; the test may briefly cause dizziness or nausea.

In India a VNG (videonystagmography) test typically costs between INR 1,500 and INR 7,000, with many diagnostic centres and private hospitals charging around INR 2,000–5,000. Final price depends on city, facility type, equipment and test components, and whether a specialist consultation or detailed report is included. Some insurance plans or hospital packages may partially cover the fee—confirm exact rates with local centres.

The Dix–Hallpike manoeuvre is the best initial test for peripheral vertigo from BPPV, provoking characteristic nystagmus. For acute vestibular loss, the head-impulse test helps distinguish peripheral from central causes. If findings are unclear or stroke is suspected, MRI (or urgent CT) and vestibular function testing (VNG/ENG, audiometry) may be needed.

Yes. Anxiety and panic can produce vertigo-like symptoms — spinning, lightheadedness, imbalance — through hyperventilation, altered blood flow, and heightened vestibular sensitivity. Anxiety can also worsen existing inner-ear problems. Because true vertigo has many causes, seek medical review if symptoms are severe, persistent, recurrent, or accompanied by hearing loss, headache, weakness, double vision, or fainting.
