Benign Hematology Specialist in Guatemala City
An abnormal blood count deserves a real explanation.
Anemias, coagulation disorders, and cytopenias are often treated empirically for years without a complete differential diagnosis. The correct treatment starts with knowing exactly what is failing and why.
When should you consult Dr. Valvert?
You have anemia that doesn't improve with iron or other treatments
Your blood count shows abnormalities your doctor hasn't been able to explain
You have recurrent thrombosis or clots with no apparent cause
You bleed easily or bruise frequently without injury
You were diagnosed with hemophilia, purpura, or sickle cell disease and want specialized care

Q475
initial consultation with complete case evaluation
Fellowship in flow cytometry. Differential diagnosis where others fall short.
With specialized training in cytogenetics and flow cytometry at Vall d'Hebron in Barcelona, I resolve cases of anemia, thrombophilia, and cytopenias that have gone months without a clear diagnosis — with a systematic approach that goes beyond the blood count.
Not all anemia is treated the same way.
Benign hematologic diseases cover a wide spectrum — from deficiency anemias to autoimmune hemolytic diseases, from hereditary thrombophilias to platelet disorders. What they have in common is that they are frequently underdiagnosed or treated incorrectly for years.
Anemia that doesn't respond to oral iron may be hemolytic anemia, aplastic anemia, or anemia of chronic disease. Thrombosis in a young person may be the first manifestation of a hereditary thrombophilia. Thrombocytopenia with no apparent cause may be immune thrombocytopenic purpura or the start of something more complex. A complete differential diagnosis is what changes the treatment — and the prognosis.
“Before treating anemia, I need to know why it exists. Iron isn't the answer for every anemia — and giving it without a diagnosis can delay the correct treatment.”—Dra. Fabiola Valvert
Symptoms that deserve a hematologic evaluation.
Many blood disease symptoms are nonspecific and are easily mistaken for other conditions. Recognizing when a symptom requires specialized hematologic evaluation can make all the difference.
Persistent fatigue
Tiredness disproportionate to exertion that doesn't improve with rest or iron supplements. May indicate anemia of unidentified cause, hemolytic anemia, or aplastic anemia.
Pallor
Pale skin, conjunctiva, or palms. A classic sign of anemia — but not all pallor is due to iron deficiency.
Excessive bleeding
Prolonged bleeding from minor cuts, very heavy menstrual periods, frequent gum or nose bleeds. May indicate thrombocytopenia, hemophilia, or other coagulation disorders.
Easy bruising
Bruising with no injury or with minimal impact. Common in thrombocytopenia, coagulopathies, and in some cases of vasculitis.
Thrombosis
Clots in deep veins (DVT), the lungs (pulmonary embolism), or in unusual sites such as abdominal or cerebral veins. In young people with no classic risk factors, it always warrants a thrombophilia workup.
Jaundice
Yellowish coloring of the skin or sclera. In a hematologic context, this is common in hemolytic anemias — caused by accelerated destruction of red blood cells.
Dark urine
Tea- or cola-colored urine. May indicate hemoglobinuria — a sign of intravascular hemolysis that requires urgent evaluation.
Pain crises in sickle cell disease
Episodes of intense pain in the bones, chest, or abdomen in patients with sickle cell anemia. Requires specialized management to reduce the frequency and severity of crises.
Do you identify with any of these?
A one-hour first consultation is enough to begin the workup and, if applicable, reach a clear diagnosis
When the blood problem hasn't found an answer.
Many patients who come to Dr. Valvert's practice have spent months or years with an incomplete diagnosis or a treatment that isn't working. In benign hematology, the correct differential diagnosis often requires specialized studies that aren't performed in a general consultation.
Anemia not responding to treatment
Chronic anemia treated with oral iron for months with no improvement. It may be anemia of chronic disease, autoimmune hemolytic anemia, pure red cell aplasia, or another cause that requires a complete differential diagnosis with morphology, reticulocytes, direct Coombs test, and additional studies.
Recurrent thrombosis with no apparent cause
Thrombosis in a young person, in an unusual site, or recurrent without classic risk factors. Requires a complete thrombophilia workup — factor V Leiden, prothrombin G20210A, lupus anticoagulant, antithrombin, protein C and S, homocysteine.
Cytopenias without a diagnosis
Thrombocytopenia, leukopenia, or anemia, isolated or combined, with no identified cause. The differential diagnosis includes autoimmune, infiltrative, and drug-related causes, and in some cases, early myelodysplastic syndrome, which requires a bone marrow biopsy.
“Anemia without a correct diagnosis doesn't improve with iron. An unidentified coagulation disorder can cost a patient their life during surgery. A complete differential diagnosis isn't optional — it's the first step.”—Dra. Fabiola Valvert
How a blood disorder is diagnosed in consultation
A complete hematologic diagnosis goes beyond the blood count. It requires peripheral blood morphology, specific studies based on the diagnostic suspicion, and in some cases a bone marrow biopsy. In the first consultation with Dr. Valvert, everything available is reviewed and what's missing is identified.
Medical history and review of prior lab work
Detailed review of prior blood counts, coagulation studies, blood chemistry, and any treatment received. In hematology, the trend of the blood count over time is as important as the current result.
Peripheral blood morphology
Microscopic review of the blood smear. Identifies red blood cell morphology (spherocytes, schistocytes, sickle cells), white blood cells, and platelets. The most informative study and the first step in any cytopenia.
Specific studies based on differential diagnosis
Depending on the suspicion: reticulocytes, direct and indirect Coombs test for hemolysis; iron panel, ferritin, transferrin, vitamin B12, and folic acid to rule out nutritional deficiencies; coagulation panel, factors, and platelet function tests for hemostatic disorders; thrombophilia workup for thrombotic events.
Flow cytometry when applicable
In cytopenias of uncertain cause, flow cytometry identifies abnormal cell populations, paroxysmal nocturnal hemoglobinuria (PNH), and other diagnoses not visible with conventional studies.
Bone marrow biopsy when indicated
In persistent cytopenias with no identified cause, suspected bone marrow aplasia, myelodysplastic syndrome, or marrow infiltration. Bone marrow aspiration and biopsy provide information no other study can.
Diagnosis and treatment plan
With the complete differential diagnosis, the correct treatment is designed — which may include specific supplementation, immunosuppression, anticoagulation, treatment of the underlying cause, or referral for transplant in cases of severe aplasia.
Why consult Dr. Valvert for blood disorders?
Dra. Fabiola Valvert
Specialized hematologist in Guatemala. Active international training and research at the highest level.
Fellowship in cytogenetics and flow cytometry
Dr. Valvert has specific training in flow cytometry and cytogenetics — the diagnostic tools that allow correct classification of leukemias and lymphomas, and other blood diseases that cannot be diagnosed with conventional studies, such as paroxysmal nocturnal hemoglobinuria.
Complete differential diagnosis
Not all anemias are due to iron deficiency. Not all thrombosis is due to immobilization. Dr. Valvert applies a systematic, complete differential diagnosis — she doesn't treat symptoms without knowing the cause.
Specialist in cases without a prior diagnosis
She has resolved cases of patients who had spent years with incomplete diagnoses — autoimmune hemolytic anemias treated as iron deficiency, undetected hereditary thrombophilias, autoimmune cytopenias mistaken for other conditions.
Comprehensive management with an on-site blood bank
Hospital Bonanova has its own blood bank, which allows for complete management of patients who require transfusions, exchange transfusions in sickle cell disease, or transfusion support during treatment.
