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.
If immediate analysis is not possible, the urine sample should be refrigerated. If the urine sample is not refrigerated, bacteria will start multiplying. The red blood cells tend to hemolyze, casts disintegrate, and the urine becomes alkaline as a result of urea-splitting bacteria. There is no reason for the specimen to be discarded.
