Overview
Laboratory tests are not diagnostic of sleep apnea. Occasionally evidence of anemia, polycythemia, proteinuria, hypercapnia, or low T4 may be found.
Sleep Apnea Laboratory Findings
Laboratory tests are not diagnostic of sleep apnea
- The following lab abnormalities may be occasionally found:
- CBC may demonstrate either anemia or polycythemia (due to hypoxemia)
- Urinalysis may demonstrate proteinuria (due to development of renal disease)
- Arterial blood gas analysis (ABG) may demonstrate hypercapnia (due to respiratory failure)
- Thyroid function tests may demonstrate low T4 concentration (due to hypothyroidism)
