Provided in the present invention is a washing-free template-ready PCR detection method for RNA. On the basis of retaining the advantages of the original template-ready PCR method, i.e., there being no need to purify and extract the RNA, no need for a reverse transcription reaction, etc., the method of the present invention designs a probe for the restriction enzymes to thereby integrate the enzyme digestion reaction, so as to eliminate the interference of various pollution sources of double-stranded DNA with no need for a washing step.
