Agar Dilution (AD) is the gold standard method for Fosfomycin susceptibility testing.
Agar dilution is also used in several applications for anaerobes and can result into a better reading with RPMI and antifungal agents if compared to other AFST methods.
The ready-to-use AD panels are available in 12 or 24-well formats, containing the antibiotic incorporated into an agar medium in different concentrations.
