The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).
The Wassermann test or Wassermann reaction (WR) [1] is an antibody test for syphilis, named after the bacteriologist August Paul von Wassermann, based on complement fixation. It was the first blood test for syphilis and the first in the nontreponemal test (NTT) category. Newer NTTs, such as the RPR and VDRL tests, have mostly
Centers for Disease Control and Prevention (CDC)-approved standard tests include the VDRL test (a slide test), the rapid plasma reagin (RPR) test (a card test), the unheated serum reagin (USR) test, and the toluidine red unheated serum test (TRUST). [2] These have mostly replaced the first nontreponemal test, the Wassermann test. [citation needed]
The Quest 2's Oculus Touch controllers. The included controllers with the Quest 2 are the third-generation Oculus Touch controllers. The design of the new controllers was influenced by the original Oculus Rift controllers. [13] Their battery life has also been increased four-fold over the controllers included with the first-generation Quest.
The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
The controllers are also rechargeable via the headset's charging dock, have a new pressure sensor for pinch gestures, and have pressure-sensitive stylus tip accessories that can be attached to the bottoms of their handles for drawing and writing. The Quest Pro controllers are also sold separately as an accessory for Quest 2 and newer. [12] [15]

The Oculus Quest 2 is bundled with a revision to the second-generation Oculus Touch controllers; they feature updated ergonomics influenced by the first-generation controllers (including reinstating the thumb rest on the rear of the controller), improved haptics, and improved battery life. They also replace the magnetic battery cover with a ...
