ctBil is slightly sensitive to pH deviations from the nominal value of pH = 7.4.
General reference: [Ref. 12]
Anticoagulants containing sodium salts give erroneously high cNa
+
results. Sodium
fluoride with or without EDTA and oxalate (disodium) affects
cGlu results. Sodium
fluoride gives erroneously high
cNa

and low cCa
2+
, cGlu and cLac results. Trisodium
citrate affects
cNa

, cK
+
and cGlu results.
Radiometer, therefore, recommends the use of heparin as the only anticoagulant.
WARNING -
Risk of erroneous results
Do not use EDTA, as it leads to erroneous pH, pCO

results. Use of EDTA will also affect subsequent measurements on the Ca
electrode and it will reduce the lifetime of this electrode.
