Nobody Particular. I think everyone know that. But not the answer to be ecpected. Because even lab for that is not easy to find, especially in third world country. Clinical lab dont do that. If there is a descent simple way like usil Lugol to check carb in food, Then Let Us Know

...cmon Mikeasaurus, even many ready packaged foods now lie with ingredients, includes many other name to represent MSG. But do you think Chinese restaurant and And Thai food Sushi place will tell you that they add MSG for their food? No, because msg is the one make people addicted. Even Italian Pizza learn that from Chinese people for there sale if you ever wonder. It's their market. People not ordering food or to eat for health for Pleasing Their Hungry Belly and especially for TASTE, because of the MSG that damage their brain and neurons.

read the ingredients?
MSG is often obfuscated from the ingredient listing, especially on products labeled for US distribution.

It could be "MSG" or "monosodium glutimate" but could also be "hydrolyzed __ protein", "autoyzed yeast", or simply "natural flavouring".

A give-away for MSG hidden as "natural flavoring" is the position of the "natural flavoring" on the ingredient list.  Ingredients are listed by weight (or perhaps volume), so something like MSG or salt would show up in the middle of the listing.
Testing for glutamate wouldn't be hard with the right indicators and some ordinary bio lab equipment (a spectrophotometer, for one). General tests for free amino acids would be even easier. It is probably not something you would do at home, however.

Glutamic acid (glutamate) is one of the 20 standard amino acids that make up all proteins. Whenever a protein breaks down, as by cooking or digestion, glutamate and many other amino acids will be released.

I think your best bet is to examine the ingredients for acid-digested, stewed, fermented, or otherwise thoroughly processed proteins. Things like soy sauce, cheese, and nutritional yeast are very rich sources of free amino acids like glutamate (and the reason those foods are so tasty.) If it tastes meaty or savory, it probably has free amino acids.
