Hi Melissa,
Perhaps Pierre (&/or Trey &/or others!) will answer you more specifically, however from Trey's info http://treyscml.blogspot.com/ for the newly diagnosed we read the following:
[How does one know if one is in accelerated phase?]
". . . The definition of CML blast phase has changed in the past few years. The World Health Organization (WHO) reclassified CML blast phase as 20% or higher, rather than the previous standard of 30%. So people are now being classified as blast phase when they formerly would have been only accelerated phase. That can be a source of confusion. . . ."
[Is it that blasts show up in the blood, or must it also be verified as being in the bone marrow?
". . . BMB is to monitor the overall health of the marrow for issues the PCR cannot monitor. BMBs look for other issues such as chromosome abnormalities, too few or too many cells (hypo- or hyper- cellular), bone cell status, blast count, presence of fibrous tissue, etc. . . ." From this we see that blast count is read only from BMB, not from peripheral blood.
[". . . can the white blood count be so high as to be considered accelerated even if the blasts aren't showing up yet, or are a small amount?"]
From my own case, I was diagnosed with WBC of 459K, normal platelets, and 4% blasts, so I was in Chronic Phase, from that it seems that WBC doesn't link to Accelerated Phase automatically.
How are you doing? You are working on a book about your life, right?

Be alert, but not overly concerned.
• Dx Oct. 22, 2008, WBC 459k, in ICU for 2 days + in hospital 1 week
• Leukapheresis for 1 week, to reduce WBC (wasn't given Hydroxyurea)
• Oct. 28, 2008: CML confirmed, start Gleevec 400mg
• Oct. 31, 2008: sent home when WBC reached 121k
• On/off, reduced dose Gleevec for 7 months
• April 2009: Started Sprycel 100mg
• Sept. 2009: PCRU 0.000
• Sept. 2011: after 2 years steady PCRU & taking Sprycel 100mg before bed, quit Sprycel (with permission)
• Currently: still steady PCRU, testing every 6 months 🤗
