Dr. Iltifat Husain’s physician take is at the end of this article
The InstaTemp MD from ARC is being marketed towards health practices as an alternative way to measure a patient’s core body temperature in a noninvasive manner. There is also a consumer version of InstaTemp, but it doesn’t measure core body temperature and has several other differences.
ARC states clinicians can simply point the device at a patient’s forehead above the eyebrows and between the eyes at a distance of 0.5 to 1.2 inches. (The patient’s forehead skin should be free of sweat or hair.) They feel the non-touch approach eliminates the need for consumables and probe covers, which helps lower costs and reduces the risk of cross contamination infection. It also eliminates the need to wake a sleeping patient to take their temperature. The device uses anti-drift, digital system-on-a-chip infrared sensor technology, is accurate within a range of +/- 0.4 degrees F (0.2 degrees C), and has a backlit LCD screen. InstaTemp MDalso contains an indicator light to signal three temperature ranges: green, orange, and red.
ARC Devices recently announced a partnership the VSee, a telehealth platform, to embed its wireless thermometer into VSee’s remote patient monitoring kits, According to Irwin Gross, CEO of ARC Devices, the partnership will allow healthcare providers to more easily integrate temperature readings into patients’ electronic health records.
Dr. Iltifat Husain’s take:
I’ve written about the accuracy of noninvasive thermometers before and how study after study has shown they are inferior to oral and rectal measurements for core body temperatures. Not only are they inferior, studies have shown wide temperature variances with them. While InstaTemp MD isn’t a traditional noninvasive thermometer, such as the temporal thermometers or tympanic thermometers — I haven’t been able to find a published study that backs up the claims made by ARC about their InstaTemp MD. Their FAQ website doesn’t offer any abstracts or published articles about the thermometer. The device is 510K Compliant and CE Certified — but that doesn’t mean it’s accurate. I’d be skeptical to use this in my practice for patients for core body temperature measurements until I see the data behind the device.
