Full-Montage Standard Electroencephalograph

What Is It?

Acquire, display, store, and archive electroencephalographic signals from the brain using a full montage array (i.e., 16 or more electrodes) and user-specified locations

What Is FDA Product Code GWQ?

Full-Montage Standard Electroencephalograph is FDA product code GWQ, Class 2, 21 CFR 882.1400.

How Does It Reach the US Market?

A 510(k) premarket notification is required before it is sold in the United States: the applicant shows the device is substantially equivalent to one already on the market. The review can be done by an FDA-accredited third party, which is usually faster. No clearance under this code names a Chinese applicant.

A registration is not a clearance: the plants above are set up to make it, and the 510(k) it is sold under is held by whoever files it, often the brand.

What Has Gone Wrong With It?

The FDA has recorded 23 recalls under this product code since 2005. None was by a company in China. The root causes the FDA records most often are No Marketing Application (3), Component change control (2) and Device Design (2).

A recall is a fact about one product and its maker, not a grade for every manufacturer of the type.
