Recently there’s been a development in the blood test we have, because if you look at -- what a lot of people talk about are treatment markers, so plethysmograph may be part of your screening test.
For colon cancers and some of the cancers, there are what we call tumour markers, which help to kind of sift through the causes. In stomach cancer, recently in the last 6 years, they developed a blood test which is slowly being wheeled out in Singapore.
It looks at the hormone level called pepsinogen. It’s a compound that’s produced in the stomach. There’s pepsinogen 1 and 2, it’s a ratio. So yes, there is a blood test that’s coming out that helps us screen through with both blood test and endoscopy.
