You can indent the text with the margin parameter, the indenting of the head can be corrected with the \offset command.

\define[1]\TestHeadCommand
  {\offset[x=-1em]{#1}}

\definedescription
  [test]
  [alternative=top,
   margin=1em,
  %headcommand={\offset[x=-1em]},
   headcommand=\TestHeadCommand]

\starttext

\input knuth

\starttest{Knuth}
\input knuth
\stoptest

\input knuth

\stoptext
