Most Pregnant Women Get Their Iron Checked. The Problem Is When.

Almost every expecting mother in Baltimore and Nottingham, MD will have her blood drawn during pregnancy. Iron gets looked at. So far, so good. The catch is timing, and it is the part of prenatal care that we, as a hematology practice, think deserves more attention than it usually gets.

Here is the short version. Standard prenatal care screens for anemia, and it does so at two points: your first prenatal visit, and again somewhere around 24 to 28 weeks. That second window is often where a problem first shows up on paper. By then you are well into the pregnancy, the baby's iron demands are climbing fast, and you are playing catch-up. The American College of Obstetricians and Gynecologists recommends iron supplementation starting in the first trimester precisely because iron need rises so early, yet many women only find out their stores are low once the numbers have already slipped.

We see the downstream version of that story often. A patient gets referred to us at 30 weeks with iron-deficiency anemia that could have been a quick fix at 8 weeks. Testing earlier, and testing the right marker, changes that.

Hemoglobin Is the Last Domino to Fall

Here is the distinction that matters, and the one that gets lost in routine screening.

A standard prenatal blood count measures hemoglobin and hematocrit. Anemia in pregnancy is generally defined as hemoglobin below 11 g/dL in the first and third trimesters, and below 10.5 g/dL in the second. Those thresholds are useful, but they catch the problem at the end of the process, not the beginning.

Iron deficiency runs in stages. First your iron stores empty out. Only later, once those stores are gone, does hemoglobin drop and anemia appear on the lab report. Ferritin is the blood test that reflects those stores, and it falls before hemoglobin does. That means a woman can have a perfectly normal hemoglobin and still be running on fumes, with iron stores already low and headed lower as the pregnancy progresses.

This is not a theory. Research has shown that a low ferritin level in the first trimester predicts who will go on to develop anemia later in pregnancy . A normal hemoglobin early on is reassuring, but it is not the whole picture. If you want to know whether the tank is full, you check the tank, not the warning light.

Why Low Iron in Pregnancy Is Worth Taking Seriously

Your body is not subtle about its iron needs in pregnancy. Blood volume rises by close to half. The recommended daily iron intake jumps to 27 mg, well above what most women get before they conceive. Your body is building a baby, a placenta, and a much larger blood supply, all at once, all from your iron.

When that demand outruns supply, the consequences are not trivial. Iron-deficiency anemia in pregnancy is associated with higher risks of preterm birth, low birth weight, and other poor outcomes for both mother and baby . Low iron can also dent your infant's early iron levels and may affect brain development. For the mother, it means worse fatigue, less reserve to handle blood loss at delivery, and a harder postpartum recovery. To be clear, these are associations, and not every poor outcome is caused by low iron. But the link is consistent enough, and the fix is simple enough, that catching it early is worth the small effort of a blood test.

The Honest Part: The Guidelines Are Still Catching Up

We are not going to oversell this, because that is not how a hematology practice should talk.

Routine ferritin testing for every pregnant woman is not yet a universal guideline. In 2024, the U.S. Preventive Services Task Force concluded the evidence was insufficient to make a blanket recommendation for screening iron deficiency in asymptomatic pregnant women , and ACOG does not currently recommend treating iron deficiency before it has progressed to anemia. There is also no single agreed-upon ferritin number that defines deficiency in pregnancy, though many clinicians act on a ferritin below 30 ng/mL.

So why are we writing this at all? Because "no consensus yet" is not the same as "no value." We work with blood for a living. When a patient has risk factors (heavy periods before pregnancy, a short gap between pregnancies, a plant-based diet, a history of anemia, or twins), a first-trimester ferritin is a low-cost piece of information that can spare a lot of trouble later. The right move is not to panic-order labs. It is to have an informed conversation with your provider about whether checking your iron stores early makes sense for you. If you want to understand what a hematologist brings to that conversation, our explainer on what a hematologist actually does is a good starting point.

What Testing Early Actually Changes

Timing changes the whole menu of options.

Caught early, low iron is usually a problem you solve with diet adjustments and oral iron tablets, taken correctly, with time to work before the third-trimester surge in demand. Caught late, oral iron may not raise your levels fast enough before delivery. That is when intravenous iron enters the picture, a treatment a hematology team can coordinate when oral iron is not tolerated, not absorbed, or simply not enough on the clock that is left. Both paths work. The early one is gentler, cheaper, and far less stressful.

That is the entire argument for testing early. Not fear, not upselling. Just more runway to fix something small before it becomes something larger.

Talk to Us Before You Need To

If you are pregnant or planning a pregnancy in the Baltimore or Nottingham, MD area and you have any history of low iron, anemia, or heavy menstrual bleeding, do not wait for a lab to flag it at 28 weeks. Reach out to the team at Brodsky Hematology and we will help you figure out whether early iron testing is right for your situation, and what to do if your stores are running low.

Iron is our specialty. Getting ahead of it is the easiest win in pregnancy care, and we would rather see you at week 8 than week 30.

What Does A Hematologist Do?

What does a hematologist actually do?

By Dr. Max Brodsky, MD · Brodsky Hematology · White Marsh, MD · May 2026

You got a referral to a hematologist. Maybe your doctor flagged something on your labs, or maybe you've been dealing with fatigue or unexplained bruising for months and someone finally said, "You should see a specialist." Either way, you probably have questions. Let me answer the big ones.

Hematologists specialize in blood

Hematology is the study of blood and all the organs it flows through. As a hematologist, I diagnose and manage conditions that affect red blood cells, white blood cells, platelets, and the proteins that control clotting. You can learn more on our What Is Hematology page.

That covers a lot of territory. Some conditions are chronic but manageable. Some need urgent attention. Most land somewhere in between.

Common reasons patients get referred to a hematologist:

Anemia, particularly iron deficiency anemia. This affects around 20 million people in the US, and many go undiagnosed for years.
Clotting disorders, including DVT (deep vein thrombosis), pulmonary embolism, and inherited conditions that make blood clot too easily or not easily enough.
Low or high platelet counts. Conditions like ITP (immune thrombocytopenia) affect how the body controls bleeding.
Abnormal CBC results. A routine complete blood count can show changes in red cells, white cells, or platelets that need a closer look.
Pre-operative clearance. Surgeons sometimes need a hematologist's sign-off before a procedure when a patient has a bleeding history or abnormal labs.
Polycythemia vera and other bone marrow conditions that affect how blood cells are produced.

A full list of conditions we treat is on the Care & Services page.

Why see a private hematologist?

Here's the reality: most hospital hematology programs are built around oncology. If you have anemia, a clotting disorder, ITP, or abnormal labs, you can end up waiting months for an appointment because the centers focus primarily on building up a robust infrastructure for cancer care, while neglecting a focus on hematology.

I built this practice to create a calm, enjoyable experience for patients with hematologic diagnoses.

You get a thorough evaluation from a team of providers who know you and understand your condition. Infusions are done in-office. Follow-up doesn't take weeks to schedule. Parking is free.

We are here to help you on your health journey.

What happens at your first appointment?

Your first visit is a consultation. I'll review your labs and medical history, ask about your symptoms and timeline, and may order additional bloodwork depending on what I'm seeing.

You don't need to come in having memorized your lab values or researched every diagnosis on Google. That's my job; you'll leave knowing what's going on and what we're doing about it.

If your condition requires ongoing management or infusions, those are available in-office. You can look at infusion services and care options on the website ahead of time if you want.

What to bring

Any recent lab work, including the CBC that triggered the referral
A list of current medications and supplements (iron, blood thinners, and NSAIDs are relevant)
A list of symptoms and when they started, even ones that seem unrelated
Your insurance card and a photo ID
Referral paperwork if your insurance requires it

If you can, have your referring provider fax recent labs to our office beforehand. I like to look at trends in your numbers before we sit down, and it makes the visit go faster.

Bring a family member if you want. A lot of patients find it helpful to have a second set of ears.

Frequently asked questions

Do I need a referral to see a hematologist? Many patients come through a referral, but you don't need one. If you're not sure whether a visit makes sense, just call the office, 410-653-4002.

Does a hematology referral mean I have cancer? No. Most of my patients have benign blood disorders — anemia, clotting issues, abnormal counts. If something concerning does come up, we let you know. But a referral by itself doesn't mean cancer.

How long is the first visit? About 30 to 45 minutes. I go through your history and explain what I'm finding. Show up a few minutes early for paperwork.

Do you take insurance? Most major plans, yes. Call ahead to verify. We also see patients on a cash pay basis.

Telemedicine? For follow-ups and lab reviews.

What is a CBC? A complete blood count. It measures red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. It's probably the most common blood test your primary care doctor orders, and it's often the thing that triggers a hematology referral in the first place.

You don't need to figure this out alone

Getting a specialist referral can feel like a lot, especially when you don't have a clear diagnosis yet. Show up, ask your questions, and let us do what we do.

If you have a referral or think you need a blood disorder evaluation, schedule online or call (410) 653-4002.
