Where to get private blood test for 3 y.o.?

[AngelDog]

I need to find someone who can take a blood sample from my 3 y.o. It's for a food sensitivity test, which is often used in the USA but I think is fairly new here.

I've been in touch with the company who are happy to do it, but who don't have anyone from their organisation who can actually do the blood test (though they are trying to find someone who can).

I've tried a private GP but this test isn't one of the normal ones they'd be able to order, as it's not standard allergy testing (which DS is having done on the NHS anyway). A nursing care organisation will do it for us, but the bureaucracy of how they work means that it'll cost about £400.

Any ideas how I can find someone to remove some of his blood so I can send it for testing?

BUPA / Spire Hospitals?

The new Circle hospitals as they are much more set up for client driven work.
It wouldn't surprise me if anyone quotes you around £400 though.

You could phone the Portland Hospital in London, they may or may not do it (they definitely do blood tests, but usually they are ordered by one of their consultants).

Thanks for the suggestions - I'll check them out.
