Use of abbreviation Greek "gamma"[edit]

I believe that the Greek letter "gamma" was sometimes used alone to represent micrograms. Assuming that I am correct about this, I suggest mentioning this as a deprecated abbreviation. Thomas.Hedden (talk) 13:28, 30 April 2009 (UTC)

I confirm, in molecular biology I have seen people using γ for micrograms, for instance to indicate a quantity of dry oligonucleotides in a tube, or to indicate a concentration together with another informal abbreviation for microliters, λ. For instance, 1 µg/µl was written 1 γ/λ. (talk) 02:46, 26 March 2010 (UTC)

Presence on Do Not Use List[edit]

Is mcg still the preferred medical use? Do-not-use list says that mcg is on the United States Do-Not-Use list. If this is the case, what is now used to indicate micrograms? (talk) 18:29, 19 May 2012 (UTC)

The list you link to is just a list of abbreviations used in medical prescriptions and hospital orders. Only the ones highlighted in red or orange are not recommended for use. Ormewood (talk) 23:21, 21 April 2014 (UTC)
