It can be of two different types: hereditary (or permanent) and acquired (or transient). Herein is described a rare case of hereditary bisalbuminemia in a healthy infant, incidentally found during elevated aminotransferase study. Despite not having pathological significance, acknowledgement of this analytical alteration is key for adequate management of these patients.engblood protein disorderelectrophoresisserum albuminjournal articlehttps://doi.org/10.25753/BirthGrowthMJ.v30.i4.20060
