Outcome Measures

Primary Outcomes (3)

  • Percent Change in Platelet (PLT) Count in Patient Blood Following Apheresis Procedure

    (PLTpre - PLTpost) / PLTpre x 100%

    on average this will be within 15 minutes after the end of the procedure

  • Percent of Processed Platelets (PLT) Which Are Collected i.e. Collection Efficiency for Platelets Achieved by Spectra Optia.

    (PLT/µL product x product volume) / ((PLTpre + PLTpost) / 2) x total processed blood volume)

    on average this will be within 15 minutes after the end of the procedure

  • Adverse Events

    during the apheresis procedure (from the moment the patient is connected until he is disconnected from the device) and device or procedure related adverse events until discharge from Apheresis Unit (On average, half hour after end of procedure).

Other Outcomes (9)

  • Patient's Platelet Count Pre-depletion Procedure

    Prior to each Spectra Optia Apheresis Procedure

  • Patient's Platelet Count Post-depletion Procedure

    Participants were followed for the duration of the procedure and an average of 2.5 hours after the procedure

  • Patients WBC Count Pre-depletion Procedure

    Prior to each Spectra Optia Apheresis Procedure

  • +6 more other outcomes

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients who have undergone platelet depletion via the Spectra Optia System and who were likely to have had blood disorders, such as essential thrombocythemia, a myeloproliferative disease, or reactive (secondary) thrombocytosis.

You may qualify if:

  • Patients having received a minimum of one platelet depletion procedure via the Spectra Optia system.
  • Availability of complete blood count results prior to starting and after completing the platelet depletion procedure via the Spectra Optia system.

You may not qualify if:

  • none
