But the big VR players are still working out motion tracking. When you look down with a VR headset on the first thing you want to do is see your hands in a virtual space. For a while, we've seen the Leap Motion accessory - which uses an infrared sensor to track hand movements - strapped to the front of Oculus dev kits.
Urine specimens should not remain unrefrigerated for longer than two hours. Aurine specimen that cannot be delivered to a laboratory within two hours should be stored in a refrigerator. The reason for this precaution is that urinesamples undergo chemical changes at room temperature.
Johnny32525 New Member. Urine should be stored in a fridge for no more than 24 hours for use in a lab analysis. Source: Britain's National Health Service (NHS): I cant post link :/ but Google NHS urine sample and you can see my source. actually have no idea how long urine can be kept at room temp, refrigerated, or frozen. I do know that I keep urine longer than 8 hours until the delivery service gets here.
