Laboratory Medicine

General Information / Add On Requests

If additional tests are required on a sample already received in the laboratory, we require evidence that a responsible clinician has authorised the additional test(s). This can be via an additional paper request form or the electronic equivalent.

Biochemistry York & Scarborough Sites

Routine Biochemistry blood samples are archived and kept for a minimum of three days. Beyond this, add-on test requests cannot be processed. 

Please note that some analytes are labile and deteriorate rapidly and some tests are not suitable for requesting as ‘add-ons’.  In these cases an add-on cannot be processed and a fresh sample will have to be taken.  Most routine Biochemistry tests are stable for 3 days. Exceptions are:

 No add-ons can be accepted for the following tests:

            Bicarbonate, Glucose, Ammonia, Lactate and HCG

 Test with 24 hour stability:

            Troponin T, D-Dimer, B12, Phosphate, Total Bilirubin, PSA

 Tests with 48 hour stability:

            Folate, Ferritin, CK, Osmolality, Direct Bilirubin

Haematology York Site

Additional examinations may be requested up to 24hrs for coagulation samples and up to 3 days for haematology samples, however requests for blood films, malaria parasite screening and ESR testing are best performed on fresh samples that are <24hrs old.  If you want to add further tests to a sample please ring (01904 72) 6802 option 1.

Haematology Scarborough Site

This procedure is designed to aid the additional analysis on haematology blood samples to ensure a full audit trail and conform with the principles of clinical governance. It is not for use with add-on test requests for urine and faecal analysis. All requests for additional tests must be accompanied by a signed request form clearly stating the tests required. This form is then used to generate further analysis. Haematology: D-Dimer and Paul Bunnell tests are only viable for 24 hours while Plasma Viscosity can be added after a maximum of 5 days.

Microbiology York & Scarborough Sites

Blood samples for serology are kept for 3 weeks, antenatal samples for 1 years. Needlestick samples are kept indefinitely. We also keep a small number of acute serum samples until a convalescent sample is received. If you want to add further tests to a blood sample we will require an additional request. Please phone 01904 726301 to make arrangements.

Most other samples are kept for at least 1 week before they are discarded.  Some samples are kept longer depending on the tests requested. If you want to add further tests to a sample please ring 01904 725721 (York) or 01723 342288 (Scarborough). We will check if we still have the sample and then add the tests. Please note that in some cases the sample may be unsuitable and we will ask you to obtain a fresh sample.

Visiting cancelled

Due to the increasing number of cases of coronavirus across the UK, York Teaching Hospital NHS Foundation Trust has made the decision to cancel all visiting to all its hospital sites in order to ensure the safety of patients and staff.

There are three exemptions to the ruling which are for one parent of a sick child under 18, for the partner of a woman giving birth and end of life patients at the discretion of the ward sister.

We would ask people to respect this decision and to treat our staff, who will be enforcing the visiting restrictions, with courtesy and respect.  For more information visit our website.


Outpatient appointments

We know that NHS services will come under intense pressure as the coronavirus spreads, and as a Trust we need to redirect staff, free up staff for refresher training and carry out any works as necessary, so we are able to maximise capacity for patients for when the number of infections peak.  We also need to reduce the number of people coming into our hospitals to protect our patients, as well as keeping our staff safe, well and able to come into work.

To do this, with effect from Tuesday 24 March 2020, along with other trusts in the Humber Coast and Vale partnerships, we have made the collective decision to suspend all non-urgent routine outpatient appointments for at least three months.  Urgent and emergency cases and cancer appointments will be carrying on as normal.

These are unprecedented times and we thank you for your understanding.  We know many people waiting for treatment will be disappointed or worried but please not contact the hospital as we will be contacting everyone directly affected in the coming days and weeks.

If you do not receive a letter or a phone call from the hospital, please turn up for your scheduled appointment as normal unless you have symptoms of coronavirus, a cold, flu or norovirus in which case you should contact us to cancel your appointment by clicking here.


Coronavirus (COVID-19)

If you have symptoms associated with coronavirus including a new continuous cough and a high temperature, you are advised to stay at home for 7 days.

Please do not book a GP appointment or attend your GP practice.

If you live with other people, they should stay at home for at least 14 days, to avoid spreading the infection outside the home.  After 14 days, anyone you live with who does not have symptoms can return to their normal routine.

But, if anyone in your home gets symptoms, they should stay at home for 7 days from the day their symptoms start. Even if it means they're at home for longer than 14 days. The most up-to-date public guidance is always online at www.nhs.uk/coronavirus

If your symptoms are serious, or get worse, NHS 111 has an online coronavirus service that can tell you if you need further medical help and advise you what to do.  Only call 111 direct if you are advised to do so by the online service or you cannot go online.
