North East London NHS Foundation Trust (NELFT) delivers the Community and Domiciliary Phlebotomy (Blood Testing).

The sites the community service will be delivered from are:

  • Silverthorn Medical Centre, 2 Friars Close, E4 6UN
  • St James Medical Practice, 47 St James St, Walthamstow, London E17 7NH
  • Langthorne Health Centre, 13 Langthorne Rd, London, E11 4HX

Patients should note that they are no longer routinely available at Whipps Cross Hospital. 

When are my results back?

Test results normally take about one week to return. All test results are seen by a doctor who assesses if they are normal or require further action. You can telephone for your results between 11-2 and 4-5 pm on 02085272563 if you would like to check about status of your results. We cannot give test results to friends or relatives unless we have your written permission.

I Have Had a Blood Test Taken so What Happens Now?

Blood tests have to be sent away to a hospital laboratory for analysis. An NHS courier collects each day around 1 pm. 

How Long Will I Have to Wait to Get My Result?

Most tests are analysed within 1 week, however, there are certain tests which require several weeks to be analysed.

How do I Get my Result?

Every result is reviewed when it arrives back in the practice by one of our clinical team. As we receive a large number of test results, it is not possible for each individual to be contacted.

If your result indicates the need for urgent attention, we will of course contact you by number you provided us on records.

For all other results, the doctor will make a comment about any action that is required. If you contact the practice, the receptionist will be able to look up your test for you and tell you what the doctor’s comment has been, including any actions that we have taken or want you to take.

If your result is not back when you contact us you may be asked to phone back, usually within the next 24 hours, to allow time for the result to be reviewed.

What Happens Next ?

If your result needs urgent action a doctor, nurse or receptionist will contact you by phone to discuss what action needs to be taken.

If your result needs action, but not urgently, the practice will ask you to contact Practice to book telephone appointment with Doctor/Nurse at convenient time for you to explain what action needs to be taken.

If no action is required the practice will not contact you but you are free to contact the practice to get your results. It is your responsibility to contact the practice if you would like to know about your results.

If you need to discuss your result with a doctor or nurse, please ask the receptionist to take a message for the doctor or nurse. They will either telephone you or you will be asked to make an appointment to see them.

It is very important that we hold an up-to-date telephone number for you. Please check with reception that we have right contact number for you as our preferred way of communication is by phone. 

How Can I Help?

It may be difficult to contact you during the day. If you have a mobile telephone number or an email address that you are happy for us to contact you on, please write your details on one of the forms at the reception desk and hand it into the reception. It is helpful to keep this information up-to-date.

Please note that results tests taken out with the practice will be returned to the requester, e.g hospital consultant.
