In reviewing the article in your January 2013 magazine "Evaluation of the Iodine Loading Test
: Urine Iodine Excretion Kinetics after Consumption of 50 mg Iodine/Iodide," by Theodore Zava of ZRT Laboratories, we think that several points need clarification.
So please disregard past information on the Iodine Loading Test
through FFP Lab and replace it with this updated information.
The proof loading test
consisted basically of 5 load steps:
(1) Whole body sufficiency for iodine is assessed by an iodine/iodide loading test
. (2) The test consists of ingesting four tablets of a solid dosage form of Lugol (Iodoral[R]), containing a total of 50 mg iodine/iodide.
Brownstein, Flechas, and Hakala regarding my publication "Evaluation of the Iodine Loading Test
: Urine Iodine Excretion Kinetics after Consumption of 50 mg Iodine/Iodide." (1) My comments below refer to some concerns raised in their letter.
The iodine loading test
was introduced in 2004 by Abraham et al.
Figure 6 shows the typical finite element model that was developed to analyze the axial loading tests
. Since PLAXIS employed an axisymmetric finite element model, 250-mm-square-concrete pile is modeled as a 300 mm in diameter axisymmetric pile, in order to optimally account for the actual square pile geometry.
The design process was not linear but a ping-pong ball discussion between initiator, engineers and contractors, testing structure and construction feasibility using real models and computer simulations, wind tunnel and loading tests
. Form and materials inevitably developed and changed accordingly.
