Avril,

 

We looked at this on an IFCC POCT committee and it is being revisited. Where there is a clearly abnormal glucose then OK and there is a move to HbA1c for screening too.

 

The IFCC committee were unconvinced that the imprecisons associated with POCT glucose meters was sufficiently tight to categorise IFG &/or IGT especially at the margins.

 

Unfortunately the NACB LMPG on POCT did not address the question you are asking, nor did the Australian GP POCT study. Consensus at the moment in don’t use meters to diagnose DM, but OK for screening.

Dear colleagues

As our GPs are being encouraged to undertake more and more oral glucose tolerance tests, more of them are doing the tests in the surgery (following the protocol provided by our laboratory). This morning I took a phone call from one GP who was interested in using POCT glucose meters to obtain the results rather than sending the samples to the laboratory.

 

Apart from the obvious facts of laboratory result vs POCT result, and the issues of capillary sampling, are there any other good reasons why POCT should not be used? Is anyone out there already doing this?

 

Kind regards

 

 

Avril
