Outcome Measures
Primary Outcomes (2)
Effects of MBL on bone marrow function
Samples collected from healthy participants and participants with MBL will be compared for differences in bone marrow function (i.e., ability to fight off infection). Results will be descriptive. With participant permission, samples will be stored for future research use.
Baseline
Effects of CLL on bone marrow function
Samples collected from healthy participants and participants with CLL will be compared for differences in bone marrow function (i.e., ability to fight off infection). Results will be descriptive. With participant permission, samples will be stored for future research use.
Baseline
Study Arms (1)
Observational
Patients undergo blood sample collection and bone marrow aspiration and biopsy and have their medical records reviewed on study.
Interventions
Eligibility Criteria
Patients with MBL, patients with CLL ,and healthy subjects recruited through Mayo Clinic.
You may qualify if:

- Remain untreated
- Are currently being treated
- Who have already been treated
- Subjects in the MBL cohort will have a clinically established diagnosis of MBL
- Healthy age-matched control subjects
- Healthy younger control subjects aged \> 40 years
You may not qualify if:
- Anyone under 40
- Healthy control subjects must not have a diagnosis of CLL or MBL
