Reflectance pulse oximetry may be used as an alternative to transmissive pulse oximetery described above. This method does not require a thin section of the person's body and is therefore well suited to more universal application such as the feet, forehead and chest, but it also has some limitations.eflectance pulse oximetry may be used as an alternative to transmissive pulse oximetery described above.

In the United States, about 2â3 million abnormal Pap smear results are found each year. Most abnormal results are mildly abnormal (ASC-US (typically 2â5% of Pap results) or low-grade squamous intraepithelial lesion (LSIL) (about 2% of results)), indicating HPV infection.
The reason a Pap test is done is to detect changes before they can become cancer. If your Pap test is abnormal, don't be alarmed. Many women incorrectly believe an abnormal Pap test means they have cancer. In fact, the cause of 90% of cervical cell changes is a virus called human papillomavirus (HPV). Most conditions detected by an abnormal Pap test are minor and easily treated in the office.
