Inaccurate haemoglobin measurement by blood gas analyzer may lead to severe adverse clinical consequences

I was most interested to read the recent very informative research paper by Altunik et al. which correlates measurement of sodium, potassium, haemoglobin (Hb), hematocrit and glucose values by blood gas analyzer (BGA) and by laboratory autoanalyzer (LAA) in over 30,000 patients [1]. As a Hematologist and Chief of Blood Transfusion at a large University Teaching Hospital, I was particularly interested to note that, although the correlation coefficient for Hb was 0.982, there was no acceptable agreement limit for Hb or for any of the other blood tests.
