I asked if an anemia with genetic characteristics might require a different diagnostic work up. general information online only repeats basic tests a hematologist might do. maybe it's not something a hematologist would diagnose? what's ife?

Question unclear: First, one's primary care doctor should be able to evaluate for anemia and see if there are any health problems that can cause anemia. A patient should always start with his primary care doctor who looks at the whole picture, so not to miss any obvious abnormalities. After preliminary diagnoses, a specialist may or may not be needed, depending on the details.
