BMI Adiponectin (µg/mL)

Intended Use: The adiponectin test may be performed on individuals at risk of metabolic syndrome or diabetes due to poor lifestyle choices.

Clinical Significance:

  • Individuals with low adiponectin levels have a 3X greater risk of developing metabolic syndrome1.
  • Men with two or more risk factors for metabolic syndrome and high adiponectin levels are half as likely to develop metabolic syndrome as men with low adiponectin levels2.
  • Individuals with low levels of adiponectin are up to 9X as likely to develop type 2 diabetes3.
  • Individuals with low adiponectin levels have a 2X increase in the prevalence of CAD4.
  • Adiponectin levels in the blood can be increased by thiazolidinediones, such as pioglitazone5.
