Công thức tính sinh khả dụng tương đối:

\(F = \frac{{{{(AU{C_T})}_{abs}}x{D_{abs}}}}{{{{\left( {AU{C_T}} \right)}_{IV}}x{D_{IV}}}}x100\)

\(F = \frac{{{{(AU{C_T})}_{abs}}x{D_{IV}}}}{{{{\left( {AU{C_T}} \right)}_{IV}}x{D_{abs}}}}x100\)

\(F = \frac{{{{(AU{C_T})}_{TEST}}x{D_{TEST}}}}{{{{\left( {AU{C_T}} \right)}_{STANDARD}}x{D_{STANDARD}}}}x100\)

\(F = \frac{{{{(AU{C_T})}_{TEST}}x{D_{STANDARD}}}}{{{{\left( {AU{C_T}} \right)}_{STANDARD}}x{D_{TEST}}}}x100\)
