A blood disorder where the body has dangerously low levels of white blood cells needed to fight infection.
Medical records that document your ANC levels over time are central to showing where your condition falls in the rating scale. Lab reports showing repeated blood counts help establish whether your ANC stays above 1500, between 1000 and 1500, between 500 and 1000, or below 500 per microliter.
Records of the treatments you receive matter just as much. Pharmacy records or physician notes showing continuous antibiotic use, prescriptions for myeloid growth factors such as G-CSF or GM-CSF and how often they are given, or records of continuous immunosuppressive therapy such as cyclosporine all help establish the level of treatment required. Hospital admission records documenting a bone marrow transplant, including the admission date and discharge date, are needed to support a 100% rating under that criterion.
Records of infections, including emergency room visits, hospitalizations, or physician notes describing the frequency of infections over a 12-month period, help show whether you meet the recurring-infection criteria at the 30%, 60%, or 100% levels. Statements from you or people who know you describing how frequent infections affect your ability to work or carry out daily activities can also help VA understand the full picture of your condition.
