Hi Sven, I remember requesting a qualitative test over the duration. It was impossible. UK NHS say they are phasing them out and won't offer them any more. I was <15 over 2 tests.
I think I did find one eventually that could detect approx <4 - 6, a private test, but that involved paying around $250+ , plus travel and the results could take up to 3 weeks to come through, so I gave it a miss. But it was the response of medics when I asked if it was possible that got me, ie a cross between bullshit and a response that suggested I had asked to go on a mission to the moon on a 5 star spaceship

As Dr Banerjee at Perspectum diagnostics (LiverMultiScan) said "Liver disease diagnostics are at least 20 years behind other conditions such as cancer and heart disease" Nothing much has changed since then as yet, unfortunately.
I feel it's not worth not taking advise at face value from Drs in a health authority or private practise. They may just not be able to access what you need. I have been totally blessed to have MonkMed / Fix HepC Drs D & F to advise me, I would ask any NHS medics (when possible as one deserted me mid tx) and Dr D & F for advise and then make my own decision after some thought to my next way forward, really, I do not know what I would have done without the latter two, I wonder how UK patients in particular deal with the stress of NHS only.
Yes, testing VL seems so variable. My current hospital is <12 Det/Und so quite sensitive but trying to get one these days seems to be getting harder. I know of a UK patient who after one post tx test, now has to wait 6 months for the next!
Meanwhile, I was told no VL test until 12 weeks post tx, so I did 'poor man's ' and have only had LFTs since EOT. Next week brings the hospital multi-test, these last days of waiting are going very slow!
Things are looking good for you, good luck with your next results.
