CDT levels, Medical facts and what the DVLA seem to want now...

Paulisme

Hi, said i would update people on my progress to my license being in my hand.... which was 27th of sept 2020.

Ban = 2 years
Breath Alcohol = 120
(Have been done twice, but not in 10 years, was made an HRO due to breath.)
CDT level via DVLA medical was 0.4% (stayed off Alcohol for 32 days prior to the DVLA medical blood test).

Now on the letter it states thus:

A %CDT result below 1.7 suggests no recent excess alcohol intake.

A %CDT level result between 1.7 and 2.2 suggests recent excess alcohol intake.

A %CDT level result between 2.3 and 2.9 indicates regular
heavy amounts of alcohol consumption and can be an indication of increasing risk or higher risk drinking.

A %CDT result of 3 or more indicates regular excess amounts of alcohol consumption and can indicate alcohol dependence.

The above is so called the traffic light system, if they allow you to drive or not or if they ask questions to your doctor for more information. I put NO to everything on the questionaire.

Now here's the rub for you all, on the actual medical test by SYNLAB it states this, i think this is VERY important for all on here:

Classic CDT (%)
DVLA Green <1.3
DVLA Amber 1.3 - 1.6
DVLA Red >1.7

So as can be seen, i think if i got over 1.4% on my test they would have gone to my doctor for a report.

So as you can now all see, they are looking for these levels and not really the ones for the one on the paper they sent to tell me my levels....

I hope this helps someone out there, any questions, just ask...

All the best

Paul

Hey Vicky, i would suggest so, but people on here say it should even be below 0.9% CDT% ... I don't really know, it may be on a person by person level and what you put on the questionaire, what you have blown and other such.... but i would take it if you're in the green they are less likely to write to your doctor, hope this helps.

YOU'RE DEFO GOING TO FAIL!!!!!!!!!

Only joking, LOL, depending if you're healthy and you liver is good etc. You will well below 0.9% imo.... how come you have not drank 4 years before that, when did you get done for drinking driving for a matter of intrest? when is your medical for the DVLA blood test Vicky?

Hi Vicky. CDT is only one of the things that DVLA look at when deciding whether to write to GP or not. If you get a 'green' level CDT, it doesn't mean that they won't write. Depending on their own notes, the DVLA doctor's thoughts, the answers to your questionnaire, whether you are on medication, whether you have ever had depression, whether it is a bad day for the DVLA bod, If it is a Wednesday etc. etc. etc.

Your best bet is to presume that DVLA WILL write to your GP. If there is any history, speak to your GP early and ensure your notes are up to date detailing your current drinking habits, last date of drink (if applicable) and get LFT's carried out to help show your liver health if there is any past discussion with any NHS service about alcohol consumption. DVLA do ask about the last 6 years with your GP, however they will also be interested in history beyond this if it is intimating any kind of alcohol dependence or misuse.

just becasue your LFT's is high, does not mean you CDT will be, esp if you have not drank since June.... also Vicky, please read what
BigTom has wrote to you, it's about the jist of things with the DVLA etc, also ask your doc what's on your notes, like Tom, it can be for the last 6 years, but then if the doc puts dependence for anything, then this could be say in 2004 and this will red flag you.... it just goes on what the doc puts on his/her questionare, by rights it's only the last 6 years, but they may put it different just to flag you..... don't worry to much in passing your CDT, you will fly through imo. you can always get a pvt test too

well you have up to 6 weeks to make an appointment, one blow out does not mean fail imo, but you can always wait for another turn, just ring the DVLA and tell them you can't get time off in the time they have given you if you're worried, 12 weeks is way long imo.... other may disagree

I think if I remember correctly, its don't book the medical until 4 days after the date of the letter as the testing centre wont have your details.
Can remember the wording being a bit confusing.

Yes, I can remember reading and thought the same as you.
I called after a week and got an appointment for about 4 weeks after, so just inside the 6 week deadline.
