Study Design

Intervention model single group assignment
Primary purpose other
Masking no masking
Commercial portable optical microscope (AM4113-N5UT Dino-Lite ) which will be employed during the study for a pre determined time of non-invasive imaging of the nailfold capillaries in ASCT patients. For Autologous Stem Cell Transplant (ASCT) participants, the imaging will be performed once prior to ASCT upon admission to the hospital, and then daily after ASCT (starting on day +7) until count recovery

Additional Information

Official title Non Invasive Optical Imaging of Capillaries Through the Nailfold for White Blood Cell Enumeration in Patients With Hematologic Malignancies
Principal investigator Yi-Bin A Chen, MD
Description The objective of this study is to obtain data that would support the use of a method to obtain WBC counts from images of small blood vessels called capillaries. These would be obtained by pressing a small device on the surface of participants' finger nails to look through the nail. These images will be obtained using a portable microscope called the Dino-Lite Digital Microscope. Having a non-invasive way to quickly measure WBC counts could be useful for a variety of healthcare applications.
