Plate count agar (PCA) is a microbiological growth medium commonly used to assess or to monitor "total" bacterial growth of a sample. PCA is not a selective medium.

The composition of plate count agar may vary, but typically it contains (w/v): [cite book |title=Handbook of Microbiological Media |last=Atlas |first=R.M. |authorlink= |coauthors= |year=2004 |publisher=CRC Press |location=London |isbn=0849318181 |pages=p. 1390 |url= ] ::0.5% peptone::0.25% yeast extract::0.1% glucose::1.5% agar::pH adjusted to neutral at 25 C.

Plate count broth does not contain agar.
