Urine can be tested via real-time reverse transcription-polymerase chain reaction (rRT-PCR) using samples collected less than 2 weeks following symptom onset. Urine should be tested in conjunction with serum if specimens were obtained less than one week following symptom onset. A positive result on either test confirms Zika virus infection. [20]
