Oral Glucose Tolerance Test Private Clinic Recommendations?

Personally, I would go back to my GP, and ask for a referral to a specialist endocrinologist who has experience in blood glucose issues, especially if you have a rare condition. Do you know the reason why your private specialist wants a glucose tolerance test?
If you don't, find out!

As for the OGTT, the two hour test is usually used to help understand why T2s have diabetes, insulin resistance and so on.
This may not tell the whole story.
In my case, I needed about ten blood panel tests during my extended OGTT (up to five hours), including c-peptide, GAD. My blood was taken prior, during and after I went hypo! My finger prick testing was every half hour, then my second and third eOGTT test every fifteen minutes.
 
Could posters please note post #6, where @Eadenhall declares a genetic anomaly leading to Beta Thallacaemia, so the usual tests my be unreliable. These tests have been requested by a private specialist.
 
I am really touched by the kindness of the people here - I cant thank you enough.

The need for the OGTT is to bypass the blood Hemaglobin as my Beta Thallasaemia trait might be interfering with the HbA1c readings. So we did the Fasting Plasma Glucose test (advised by my GP as they dont do the OGTT there) and my Specialist is recommending I do the OGTT privately.

I have heard back from Medichecks and they can either offer me their OGTT with the following:

Fasting Glucose
Blood Glucose (0.5 Hrs)
Blood Glucose (1.0 Hrs)
Blood Glucose (1.5 Hrs)
Blood Glucose (2.0 Hrs)
+ 1 Insulin test (additional £49)

or their special package 'Glucose Tolerance and Insulin test' which is the following:

Fasting Glucose
Blood Glucose (1.0 Hrs)
Blood Glucose (2.0 Hrs)
Insulin (1.0 Hr)
Insulin (2.0 Hr)

So the second option loses the blood glucose tests at 0.5 hour marks, but includes the two insulin tests.

Which might be the best option for me out of these two?

My sincerest thanks

David
 

This is not a recommendation; it can only be your decisions, if you elect to compromise, but we're I in your shoes, I would choose the latter, but in the meantime, I would buy a blood glucose resting kit and strips, and test my blood every 15 minutes through the OGTT. A finger prick test only takes seconds to perform but would go some way towards filling in the blanks.

Are you rejecting the C-Peptide test?

I hope you can secure the discount too.
 
During the Specialist's appointment he mentioned the C-Peptide test, but said that we can do the OGTT and see what the result is first before seeing if the C-Peptide test is required. However, I must say that after being on here, I have far more faith in the opinions of you guys! I very much feel the 'sales' mentality of his team.
 
Personally, and you do have to make your own decisions.
I would get the insulin tests before the c-peptide.
The insulin response to the glucose is often overlooked and could explain a lot of the issues that certain people can experience.

But, I would still ask my GP for a referral.
 
With absolute thanks to everyone that has taken their valuable time to help me, I have now booked the OGTT and the Insulin test.
I wouldn't have known where to begin here, and with your help I feel so much more confident about all this.
Is it bad etiquette to return here after my tests if I am confused on certain results? I dont want to outstay my welcome.

My sincerest thanks

David
 

I think people will be interested to see/hear your results.

Edited to make it make sense. Autocorrect has much to answer for!

Please do!
In certain that a lot of information can be gotten from the results.
Ask and record your blood glucose readings as they are done, before and during the test.
If it is a standard two hours test, it might be prudent to test afterwards, to see what happens at two and a half, three hours, and four hours.
Because my condition is quite rare, I have had quite a few eOGTT tests. It helped with understanding what, why and how my body does what it does when I eat or drink.
This, I believe is what you are after, answers.

Best wishes
 
I am only just seeing this. What happened and did yo find somewhere to get test done? I have contacted BioLAb as I want a 4 hour glucose tolerance test so I can work with E-4 Alive in the States, so do much more detailed test than just the Hba1c! I did keto and it did me no good, so I need some more informed advise than you get form the GP.
 

This is a thread more than a year old, the OP never came back to tell us the results.

I can only assume that you don't want to start a thread, so that it is seen by more people.
In response, why do you need a extended OGTT?
As far as a vegan diet, I'm not going to be any good at all.
But I have heard it is quite difficult to stay low enough on a vegan diet.
I can only imagine that you didn't go low carb enough to make a difference.

With type two, you need a balance of protein and good fats, with carbs that your blood sugar levels can tolerate, without causing more insulin resistance and spiking high.

Hope this helps.
 
Perhaps explaining where you are geographically would help as this is an international forum. Not much use getting details for another country.

What is E4 alive? and why is an extended OGTT is necessary? Why wasn’t keto wasn’t good for you ? This might get you some helpful replies too.
 


Hi David
Hope all goes well with you
Can you please kindly share the clinic you went to for the tests mentioned above ( presume this is somewhere in London?)
I have emailed Medichecks, they came back to me in few hours unfortunately they don't offer OGTT test ( anymore ?)
The only one they are doing at the moment is
Insulin Resistance Blood Test
I am about to email them back to find out as what is included in the test
I am new to this area please bear with me if any silly questions
Thanks for your help in advance
Kind Regards
Danni
 

Hi and welcome to the forum,
Can I ask for more details as diabetes is not usually diagnosed through an oral glucose tolerance test.
Or was your last GP asked you to get one done?
If you have just moved, you can register to a new GP, get an appointment and see what your new GP says

Stay safe
