This looks more like the monitoring required for Methotrexate therapy, rather than steroids. You will need a conventional anticoagulated sample for FBC at least and the issue then is how you get an adequate capillary sample for the rest as well. I have previously used a bleeding time device rather than a conventional lancet to get a good volume- you press the device firmly against the finger and blood drips out of the small cut. Its a good way to get out of the washing up too.
Many haematology labs no longer use the devices so access to them may be a problem.

Subject: POCT LFT
Dear mass brain,
We have a patient with an intractable fear of needles - apparently can
not even discuss it with her clinician.
This lady requires steroid therapy for rheumatoid arthritis - and thus
minimum monitoring with creatinine, FBC and LFTs.
She has agreed to have finger prick tests..
Is anybody doing LFTs on finger prick samples?
Even if by blood spot in a lab..
I do not want to organise bringing in a new piece of equipment to the
Trust for this one patient. The cost implication would not justify it.
So any laboratories doing a blood spot LFT?
Or even if there are any local hospitals (London area) offering a finger
prick option - the clinician is prepared to refer them on..
I have suggested hypnotherapy.
Many thanks
Katy
