Dear all,
Has anyone any explanations for these results:
DPC Immulite 2000
Date Free T4 TSH
15/10/02 8.4 50.9
Patient put on 50 ug T4
30/10/02 8.8 35.2
25/11/02 <2.6 2.59
17/12/02 <2.6 4.43
(Cortisol 193 nmol/L Testosterone 8.7 nmol/L)
27/1/03 Heparin <2.6 9.0
Serum <2.6 8.6 LH 2.5 FSH 2.1
EDTA <2.6 6.32
Bayer Centaur - measured by colleagues elsewhere.
17/12/02 10.3 30.36 Prolactin 171
27/1/03 Heparin 10.3 36.74 Prolactin 169
Serum 10.1 35.87
Patient is male, dob 3/2/33. He has Parkinson's, Coeliac disease ,
Essential hypertension, Pernicious anaemia. He has been prescribed
propanolol,citalopram, thyroxine, and B12 injections 3 monthly. He has
recently started taking glucosamine as an over-the-counter prepn.
On the 27th we bled the chap in the department. Prelim expts had
suggested that EDTA may slightly lower Immulite results and we wondered
if the samples in November/December had been decanted by the surgery
from EDTA samples into heparin tubes. However the effect was
insufficient to account for these discrepancies and this was proved on
the last set of samples.
What can explain these method-dependent differences ?
A very puzzled Jeff Slater
