|Sickle Cell Disease|
This is an observational study of sickle cell patients with the aim to measure exhaled carbon monoxide levels and to correlate with genotype and standard clinical markers of hemolysis.
Upon enrollment and at each subsequent visit, if acceptable to the patient, each subject will undergo measurement of exhaled carbon monoxide utilizing a hand held carbon monoxide monitor, MicroCO/Smoke check. Subsequent evaluations may be obtained during a routine visit, while hospitalized for a vasocclusive crises (VOC) episode, or when evaluated in the acute care clinic.
The principal study objective is to assess if exhaled carbon monoxide levels are a non-invasive marker of hemolysis in subjects with sickle cell disease (SCD).
The secondary study objective is to assess exhaled carbon monoxide levels serially in subjects with SCD, relative to vasocclusive crises, transfusion requirements, and pain syndromes.
The one inclusion criteria is for all adult sickle patients presenting for follow up at the outpatient sickle cell clinic who are capable of following simple instructions.
The exclusion criteria are a recent (2 week) history of lung infection, asthma, acute chest syndrome, or COPD exacerbation and/or a significant pulmonary dysfunction in the recent (3-6 month) past.

Sickle Cell Patients
Patients with Sickle Cell, over 18 years of age
- Exhaled Carbon Monoxide Level and hemolysis markers [ Time Frame: Participants will be followed for the duration of two years, at baseline clinically, or while hospitalized for a VOC episode, or when evaluated in the acute care clinic for pain or symptom exacerbation. ]Exhaled Carbon Monoxide Levels will be measured serially, at clinical baseline and with symptom exacerbation.
