It is common for people to ask which blood tests they need to fast for before providing the blood sample. The main tests that require fasting are the blood glucose test (which can be used to diagnose diabetes) and the cholesterol blood test. Iron levels are also ideally checked after fasting.
If you require a fasting blood test it is advisable to have it first thing in the morning after fasting overnight. Then have your breakfast after the test. Many patients choose to book their GP appointment for a different time of the day. Your doctor can then discuss your symptoms with you and if a fasting test is required they will arrange the test for you. This can be carried out at our partner laboratory in central London at a time of your convenience.
Please note: a GP consultation fee is payable online at the time of booking. Any tests which you require will be chargeable on top during your consultation with the doctor.

This is only a small sample of the many blood tests which DocTap provide. Our expert doctors can advise you during your consultation on the most appropriate tests for your condition. View all blood tests.
DocTap seek to provide the most convenient, fastest, effective and best value private blood testing service in London. With 12 blood test centres across London and same day appointments available 7 days a week, it has never been easier to book a fasting blood test. We are proud to partner with The Doctors Laboratory (TDL) which has a worldwide reputation for excellence.
Unlike many blood test clinics, you will see a UK accredited GP who will be able to offer their expert option on what test is most appropriate for you. Your results will also be accompanied by a written analysis of what they mean and what your doctor advises you to do next. Should additional treatment be required, or if you simply wish to discuss the results in more detail, then you can book a 15 minute follow up consultation for only £25. This can either be at any DocTap clinic or over the phone. When booking your follow up consultation you can request to see you original doctor if you wish (subject to their availability).
Should you require a full consulation before deciding to have a fasting blood test then there may be insufficient time to also take a blood sample in the appointment. In that case you can choose to either go to our walk in laboratory by Oxford Street (£15 phlebotomy fee applies) or to make a second appointment for the doctor to take the bloods.
The glucose test is used to diagnose diabetes but increasingly a different blood test called the HbA1c test is used, this doesn't require fasting.
A cholesterol check looks at the total level of cholesterol, the 'good cholesterol' (HDL) and 'bad cholesterol' (LDL). Your doctor will advise whether you need to fast for a cholesterol check. Fasting is necessary if your doctor wants to include a check for a different kind of fat called triglycerides.See a GP for a Fasting blood test now
