HEALTH AND SAFETY REQUIREMENTS 5.1 Collection, labelling and dispatch of specimens Staff responsible for the collection of specimens and transporting them to the laboratory for investigation are responsible under the Health & Safety at work Act and the COSHH regulations to do so in a safe manner. A common high standard of Health and Safety must be applied to all samples. This includes using appropriate specimen containers and sealing the container in the bag attached to the request card. Strict national (DOH) and international (WHO) regulations are applied to the transportation of infectious materials (including clinical specimens) by road or post. 5.2 High Risk specimens Specimens from individuals known, or suspected of Blood Borne Viruses (BBV) eg. Hepatitis B or HIV should have the following information included on the Specimen(s) and Request Card: A ‘Danger of Infection’ label attached to each specimen and on the accompanying request card. Clinical details on the request form should be adequate to convey information of the suspected hazard to the staff who handle the specimens. To maintain patient confidentiality during transit to the laboratory, it is recommended to seal the specimen and request in a suitable envelope. Specimens presenting a risk of BBV Include: Blood CSF Urine Other body fluids Haematology Department Pathology at Wigan and Salford Title: Information for users of the haematology department Q-Pulse Ref: Authorised By: HH-INF-39 Q -Pulse Revision No: 6 Page 7 of 19 D Seddon 6. INSTRUCTIONS FOR COMPLETING REQUEST FORMS It is the responsibility of the requesting clinician to ensure that samples are correctly labelled and request forms completed to the agreed standard. Standard operating procedures for the receipt of samples and request forms are put in place to ensure the safety of the patient. They are intended to ensure that the appropriate investigation is performed on each sample. Clinical details must also be provided. Before accepting a clinical specimen, laboratory staff must ensure certain minimum criteria for sample identification are met. The table below outlines the acceptable minimum required information to identify a specimen on receipt in the laboratory. Without this minimum information the sample will only be processed in exceptional circumstances. Please refer to the Specimen Acceptance Policy on SRFT Synapse or the Pathology Collection, Transportation and Receipt of Clinical Specimens Policy on WWL intranet. Samples must be labelled with at least TWO unique identifiers from: Patient’s Full Name i.e. Forename and Surname NHS number Date of birth Hospital number Samples that are not labelled with at least two unique identifiers will not be processed Samples must be accompanied by a request form. The request form MUST have at least TWO unique identifiers. The information on the sample must match what is on the request form. Haematology Department Pathology at Wigan and Salford Title: Information for users of the haematology department Q-Pulse Ref: Authorised By: HH-INF-39 Q -Pulse Revision No: 6 Page 8 of 19 D Seddon We can generate Pathology reports most effectively when the request form is completed with the following information: The patient’s location/destination for the report- this can be a location code Test required Name of consultant or GP Name of the requestor and contact number (bleep or extension) Patient gender Date and time of specimen collection Anatomical site and type of specimen (where relevant) All relevant clinical information Patient address for GP requests When your patient is going to label the sample container please advise them of the labelling requirements. The sample container must also contain the date of collection. 7. CLINICAL ADVICE AND INTERPRETATION Haematology Medical staff are available to give advice at all times. They can be contacted via telephone during the normal working day and via switchboard at all other times. 8. UNCERTAINTY OF MEASUREMENT All biomedical results are subject to a degree of uncertainty. This is due to biological variation, analytical measurement imprecision and pre-analytical factors (sample stability etc.). If you are concerned about the confidence limits and interpretation of an individual result please contact the Haematology department. 9. SERVICES DESCRIPTION The department treats patients referred within the North West sector of Greater Manchester (Bolton, Wigan and Salford).

ADDITIONAL CLINICAL INFORMATION 12.1 Oral anticoagulation treatment SRFT please refer to Trust Oral Anticoagulant Policy WWL please refer to Trust Anticoagulation Guidelines 12.2 Thrombophilia investigations Investigation of patients for an inherited marker of Thrombophilia is frequently unnecessary and seldom has a significant impact on the clinical management of a patient. It may be considered, along with other tests, in the following circumstances: Spontaneous venous thrombosis at <45years age. Venous thrombosis at unusual sites. A strong family history of venous thrombosis. A history of recurrent fetal losses. Patients should first have a full clinical assessment for evidence of an acquired cause for a prothrombotic tendency, as well as a full blood count to exclude such conditions as iron deficiency, myeloproliferative disorders, haemolytic anaemia and PNH. Screening for a Lupus Anticoagulant/Anti Phospholipid Syndrome should be considered in all patients with recurrent fetal losses or an apparent tendency to venous and/or arterial thrombosis. A screen for inherited markers of a predisposition to venous thromboembolism, if indicated, will include tests for Activated Protein C Resistance, Antithrombin III, Protein C and Protein S. Avoid taking the relevant samples around the time of an acute thrombotic event or when the patient is receiving anticoagulant therapy.
