Body system 107.00 in the SSA Blue Book covers blood and hematological disorders for children (Part B). SSA uses these listings at step 3 of its five-step disability evaluation. If your medical evidence meets one of the listings on this page, your claim is approved without the disability examiner moving on to past-work and labor-market analysis at steps 4 and 5.
Most claimants who do not meet a listing in this body system can still be approved at later steps based on their residual functional capacity, age, education, and past work. The medical evidence you build for a listing-match argument is the same evidence those later steps rely on, so the listing criteria are useful to read even when a claim looks like a step-5 approval candidate.

How SSA describes this body system
Excerpted from SSA's regulatory introduction at the top of the body-system page. Full text and all subsection cross-references live on ssa.gov.
Hematological Disorders A. What hematological disorders do we evaluate under these listings? We evaluate non-malignant (non-cancerous) hematological disorders, such as hemolytic anemias ( 107.05 ), disorders of thrombosis and hemostasis ( 107.08 ), and disorders of bone marrow failure ( 107.10 ). These disorders disrupt the normal development and function of white blood cells, red blood cells, platelets, and clotting-factor proteins (factors). We evaluate malignant (cancerous) hematological disorders, such as lymphoma, leukemia, and multiple myeloma, under the appropriate listings in 13.00 , except for two lymphomas associated with human immunodeficiency virus (HIV) infection. We evaluate primary central nervous system lymphoma associated with HIV infection under 114.11B , and primary effusion lymphoma associated with HIV infection under 114.11C . B. What evidence do we need to document that you have a hematological disorder? We need the following evidence to document that you have a hematological disorder: A laboratory report of a definitive test that establishes a hematological disorder, signed by a physician; or A laboratory report of a definitive test that establishes a hematological disorder that is not signed by a physician and a report from a physician that states you have the disorder; or When we do not have a laboratory report of a definitive test, a persuasive report ...

What happens during a claim under 107.00
The disability examiner assigned to your claim looks for medical records that match the lettered criteria of one of the listings above. The examiner does not diagnose you and does not weigh symptoms in isolation. They line up the listing's required findings against your records and decide whether the records contain enough to satisfy the listing as written.
If your records meet a listing, the claim is approved at step 3. If not, the examiner moves on to evaluating your residual functional capacity (RFC) at steps 4 and 5. RFC is a description of what work activity you can still do despite your impairments. The listings inform the RFC because the same medical evidence the listings ask for is the evidence the examiner uses to write the RFC. The disability overview walks through the full five-step evaluation in plain English.
Work activity, SGA, and the SSDI gate
A claim under any Blue Book listing is denied at step 1 if you are working at or above the substantial gainful activity threshold. SGA is the monthly earnings test SSA applies before any medical evaluation. Earning above SGA in countable work activity means SSA never reaches the listings on this page. Earning below SGA, or being out of work entirely, lets the medical evaluation proceed.
Once you are approved and receiving SSDI, the trial work period and extended period of eligibility apply differently than at the initial-application stage. Both are explained on the SGA amount page with year-by-year thresholds since 1975.
Adult listings for the same body system
SSA publishes a parallel body system at 7.00 for the adult (18 and over) side of the same conditions. Many listings cross over with tighter functional thresholds for the children's version. The Hematological disorders page covers the 5 active listings on that side.
