The digene HPV test, the first FDA-approved HPV test, tells you and your healthcare provider whether you have one or more of the 13 most important high-risk types of the virus-16,18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68. (Although QIAGEN also makes a test for low-risk HPV types, its routine use is not recommended in medical guidelines or reimbursed by insurance.)
Currently, the digene HPV Test does not tell you specifically which high-risk type(s) of the virus you have. However, under existing medical guidelines, the extra exams and other follow-up care you should get are the same no matter what type of high-risk HPV you have.
That may change in the future. QIAGEN and other companies are developing additional, follow-up tests that could, for example, determine whether you have HPV 16 and/or 18 – the types that cause about 70 percent of cervical cancers.
Cervical collars are also used therapeutically to help realign the spinal cord and relieve pain,  although they are usually not worn for long periods of time.  Another use of the cervical collar is for strains , sprains or whiplash .   If pain is persistent, the collar might be required to remain attached to help in the healing process.   A person may also need a cervical collar, or may require a halo fixation device to support the neck during recovery after surgery such as cervical spinal fusion .
