To book a GTT at God Hope please telephone Katherine Taylor (ext 47246) or Mandy Simpson (ext 49253). Alternatively complete a biochemistry request form with GTT in the additional tests box and send via post or internal mail to one of the above.
Glucose Tolerance Tests
Appointments can be made via Diabetes Centre on 0121 424 0234. A service is available at Solihull - for information contact Laboratory Reception at Solihull on 0121 424 5531 / 0121 424 5526.

Only the fluid types below and specific analyses tabled are now allowable in Telepath and ICE. Where a fluid type or analysis is not allowable in Telepath please book as miscellaneous and then contact the Duty Biochemist before analysis is performed.
All fluids must be centrifuged and then analysed only if free from particles.
Conventionally diabetes mellitus has been diagnosed by high fasting or random blood glucose concentrations, or abnormal oral glucose tolerance tests (OGTT). Haemoglobin A1c (HbA1c) has been used to monitor longer term glycaemic control in patients with known diabetes mellitus.
In 2011, the World Health Organisation (WHO 2011) recommended that HbA1c measurements should also be used to diagnose diabetes in the majority of asymptomatic individuals, and this recommendation has been agreed in the UK (NHS Diabetes 2011).
HbA1c of 48 mmol/mol or more (≥ 6.5%) is consistent with diabetes: if the patient has no symptoms then a second HbA1c result must be obtained within 2 weeks, and if ≥ 48 mmol/mol (≥ 6.5%) confirms diabetes mellitus.
HbA1c values of 42 to 47 mmol/mol (6.0 to 6.4%) suggest a high risk of future diabetes. Such individuals should be offered structured lifestyle education and support to delay/prevent development of diabetes, and have an annual HbA1c test
Before undertaking any biochemical investigations which are to be conducted as part of a research project or clinical trial, the protocol and workload entailed must be discussed with the Department. Failure to do so may jeopardise the project at a later stage with unfortunate consequences.
