The correct answer is the final option - sickle cell disease and malaria are both potentially lethal diseases.
The other options are incorrect because sickle cell disease is an inherited disease, but malaria is not - it is an infectious disease. However, both of these disease are quite dangerous, and may have severe consequences (such as death) if they are not properly treated.
The answer is 200 cells per microliter
Fever, weight loss, and candida infections are symptoms of immunodeficiency. These symptoms only appear if the level of CD4+ count is below normal, resulting in disruption of the immune cells work. The threshold level of CD4 count to cause immunodeficiency symptoms is 200 cells per microliter.
Answer:A submitter of a premarket notification submission (510(k)) must demonstrate to the Food and Drug Administration (FDA) that the “new device” is “substantially equivalent” (SE) to a legally marketed predicate device. This guidance is intended to help 510(k) submitters demonstrate substantial equivalence. This guidance does not add new regulatory requirements for submitters, it does not change the 510(k) premarket review standard nor does it create extra or new burdens on what has traditionally been submitted in 510(k)s. FDA developed this guidance to improve the predictability, consistency, and transparency of the 510(k) premarket review process. Furthermore, this document is intended to serve as an aid for evaluating the benefit-risk profile of a new device in comparison to the predicate device.
