interp_extrap_conc_method {PKNCA}

Interpolate or extrapolate concentrations using the provided method

Description

Interpolate or extrapolate concentrations using the provided method

Usage

interpolate_conc_linear(conc_1, conc_2, time_1, time_2, time_out)

interpolate_conc_log(conc_1, conc_2, time_1, time_2, time_out)

extrapolate_conc_lambdaz(clast, lambda.z, tlast, time_out)

Arguments

conc_1, conc_2

The concentration at time1 and time2

time_1, time_2

The time value associated with conc1 and conc2

time_out

Time when interpolation is requested

clast

The concentration at the last time above the lower LOQ

lambda.z

The elimination rate (in units of inverse time) for extrapolation

tlast

The time of the last concentration above the lower limit of quantification (LOQ)

Value

The interpolated or extrapolated value using the correct method
