Flashcards in Laboratory Medicine (Diagnostic Techniques) Deck (7)

List the reasons for requesting laboratory investigations

• To inform the clinical decision
• Screening
• Diagnosis
• Confirmation or rejection of clinical diagnosis
• Monitoring
• Natural history or response to treatment
• Prognosis
• Prediction of course or outcome of the disease


List some individual laboratory medicine specialities

• Clinical Biochemistry
• Immunology
• Microbiology- diagnosis and monitoring response
• Haematology
• Histopathology / Cytopathology
• Genetics


Describe the essential information required when taking a sample from a patient

• Full ten digit CHI number
• Patient’s surname
• Patient’s forename
• Date of birth
• Specimen type
• Anatomical site
• Investigations required
• Date & time of collection
• Relevant clinical history
• Patient location
• Full name of requesting practitioner
• Contact details of practitioner
• Patient’s home address
• Laboratory specialty sample is being submitted


Why is the correct patient information required?

• It allows the laboratory to produce the right result, on the right patient, at the right time.
• Allowing clinicians to give the right treatment in a timely manner!


Describe the MDT approach involving laboratory medicine for patient care

• Medical staff at clinic
• Phlebotomist
• Laboratory staff (Biochemistry, Genetics)
• Genetic counsellor
• Dietician
• Nurse specialist


What is POCT?

• POCT (point-of-care testing) is laboratory testing performed in the clinical setting by non-laboratory healthcare professionals.
• E.g. blood gases, urine dip sticks, blood glucose tests, urine analysis machines


Why is POCT useful?

• Improved turnaround time
• Potential for better monitoring of certain conditions
• Smaller sample volumes
• Less clinically invasive
• In some out-patient settings, POCT results can be used to adjust patient’s medication resulting in less frequent clinic appointments
