You had bloodwork done at Suburban Hospital or Sibley Memorial last month. Ferritin came back at 19.
Your doctor said "watch it, retest in six months." You're still doing the Norwood or Bullis School drop-off before eight, stuck on the Beltway or River Road, and by carpool pickup you're running on nothing. Most Potomac patients we see aren't diagnosed with anemia.
They're sitting in the ferritin gray zone, iron stores between 15 and 30 ng/mL, where hemoglobin reads normal but the exhaustion is real. Focus slips by early afternoon.
Hair thins more than it should. A full night's sleep stops fixing anything, and nobody's connected it to iron. Many primary care doctors near River Road and Potomac Village mention low ferritin in passing at an annual physical, but rarely offer an infusion on the spot or explain what the gray zone actually means. Oral iron takes three to six months to work, if the stomach cramps don't make you quit first. A visit to an infusion suite at Suburban or Sibley eats half a day between parking, check-in, and a waiting room, then the drive back down River Road at rush hour. Hard to justify with a school pickup waiting.
