259:, which is a protein produced by the kidneys in response to poor oxygen delivery. As a result, more erythropoeitin is produced to encourage red blood cell production and increase oxygen-carrying capacity. This results in secondary polycythemia, which can be an appropriate response to hypoxic conditions such as chronic smoking, obstructive sleep apnea, and high altitude. Furthermore, certain genetic conditions can impair the body's accurate detection of oxygen levels in the serum, which leads to excess erythropoeitin production even without hypoxia or impaired oxygen delivery to tissues. Alternatively, certain types of cancers, most notably renal cell carcinoma, and medications such as testosterone use can cause inappropriate erythropoeitin production that stimulates red cell production despite adequate oxygen delivery.

When hematocrit levels are lower than that percentage, the MAP decreases in response, which may be due, in part, to the increase in viscosity and the decrease in plasma layer width. Furthermore, affected individuals may have other associated conditions alongside

Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. The definition is different for neonates and varies
