An elevated serum alpha-fetoprotein or α-fetoprotein level before orthotopic liver transplantation is predictive of mortality after orthotopic liver transplantation for hepatocellular carcinoma.

So, what do you think? Would you use alpha-fetoprotein or α-fetoprotein? Here’s the answer (use your mouse to highlight the text box):

An elevated serum α-fetoprotein level before orthotopic liver transplantation is predictive of mortality after orthotopic liver transplantation for hepatocellular carcinoma.

The AMA Manual of Style recommends the use of Greek letters rather than spelled-out words, unless usage dictates otherwise. Consult Dorland’s and Stedman’s medical dictionaries for general terms. These sources may differ in the representation of terms, ie, α-fetoprotein (Stedman’s) and alpha fetoprotein (Dorland’s). If the Greek letter, rather than the word, is found in either of these sources for the item in question, use the letter in preference to the word (§17.1, Greek Letter vs Word, p 781 in print).
