Clinical Scenario

This example is based on the following Pathology scenario

Description

Lisa Stanner, a 60 year old woman, attends Manor GP Practice for monitoring her hypertension. Lisa’s GP, Dr Jane Green, requests renal function tests (electrolytes and creatinine profile). The request is sent electronically using an order comms system (accessed via the GP practice system) to the pathology laboratory based in the local hospital, Midtown District Hospital.

Dr Green books an appointment with the practice nurse, Alice Jones. Lisa attends the appointment the following day where the blood sample is taken and sent to the laboratory.

The sample is received by the laboratory, checked and matched with the test request. The details are recorded on the Laboratory Information Management System (LIMS).

The tests are performed, and the results are authorised for release. The following test results (and reference ranges) are sent electronically from the LIMS to the GP practice system:

Electrolytes and Creatinine Profile

Type Units Range
Sodium 142 mmol/L (133 to 146)
Potassium 4.8 mmol/L (3.5 to 5.3)
Chloride 105 mmol/L (95 to 108)
Creatinine 64 umol/L (48 to 128)
EGFR 87 mL/min/1.73m2
Comments The EGFR quoted above must be multiplied by 1.2 if the patient is of Afro-Caribbean origin.
