The normal temperature of human urine ranges from 94Â°F to 96Â°F (about 35 Â°C). The temperature of drug test sample must be measured during first 4 minutes after it was received, as it changes depending on ambient temperature. Acceptable range is from 90 Â°F to 100 Â°F (32 Â°C - 38 Â°C) , any sample with a temperature out of this range will immediately fall under suspicion.
Now, in 2017, most labs test for it, so synthetic urine without uric acid will most likely fail. Sample must have body temperature. Itâs about 90-100Â°F or 32-38Â°C. Thatâs why proper products include temperature strip and heating pad.
