Methemoglobin, myoglobin, and methemalbumin can cause abnormal dark color in patient samples.
Of these potential causes, methemoglobin and methemalbumin have absorption properties that give the blood a brown or chocolate brown color when present in sufficient amounts (1).
When the haptoglobin is saturated, the excess hemoglobin (usually now in the oxidized methemoglobin form) will release free ferriheme, which first binds to albumin, forming methemalbumin, followed by transfer to another protective plasma protein, hemopexin.
However, observations made after blood transfusions should always interpreted with caution in light of the complexation of albumin with the heme from the transfused erythrocytes [7], which gives rise to additional bands of methemalbumin on the gels.
