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.
What they represent, generally speaking, is the likelihood that cervical cancer is present with normal being the lowest likelihood and HSIL being the highest likelihood of cancer. The American College of Obstetricians and Gynecologists (ACOG) published guidelines in 2006 for the management of abnormal Pap smears.
