1. A method for detecting whether at least one molecule of a target nucleic acid is:

  • present in a first sample portion, said method comprising;

    loading a first sample portion into a first sample chamber, said first sample portion comprising at least part of a sample, whereby if said first sample portion contains at least a single molecule of said target nucleic acid, said first sample portion would attain a detectable concentration of said target nucleic acid within a portion of said first sample chamber after a single round of amplification, said first sample chamber comprising means for minimizing diffusion of said first sample portion;

    subjecting said first sample portion in said first sample chamber to at least a first amplification step; and

    thendetermining whether said first sample portion contains at least one molecule of said target nucleic acid.
