A 74 year old female has been admitted to your ICU with urosepsis. She is previously well with no previous hospital admissions. She was commenced on prophylactic subcutaneous heparin on day one of her admission and the following blood results were obtained:
|Parameter||Patient Value||Adult Normal Range|
|Haemoglobin||10.1 g/L*||9.8 g/L*||9.6 g/L*||120.0 - 160.0|
|White Cell Count||18.4 x 109/L*||14.2 x 109/L*||10.5 x 109/L||4.0 - 11.0|
|Platelet count||120 x 109/L*||101 x 109/L*||88 x 109/L*||150 - 350|
On day three, one of your trainees performs a "HITTS screen" which is reported as positive. The patient has remained clinically stable.
Describe your approach to this situation and give a rationale.
