It's the same test from everything I know. The test kit is what you use to to preserve the sample you take from someone.
The sample is then tested in a lab in a PCR. Funnily enough, my friends company in the middle are looking at supplying the kits from South Korea in different countries in the middle east. He sent me the sales pack for it
So I was looking at this sales pack again, and it seems like the biggest bottleneck is that the PCR test takes ~ 2 hours to run.
And just looking online - most PCR machines are designed in a "96 well format" i.e. tests 96 samples in one go.
So one machine across a 3-shift pattern ~ 80% total productivity can carry out about a 800 tests per day.
Again looking online - one of these things costs about $25k USD. At the moment we have the capacity for 16,000 tests per day so to get to about 100,000 per day it will take another ~105 of these machines which is about $2.6m USD. Demand is probably quite high though & you have to factor in other costs such as the kits, labour, labs. Luckily we do have a lot of labs in this country - our universities definitely have the capability to support this on that type of scale.
