26 Possible Causes for HbA2 Elevated

  • Microcytic Anemia

    This cell is: a) Normocytic b) Microcytic c) Macrocytic You detect elevated levels of HbA2 in the blood of a patient. You suspect what type of disease process?[sporcle.com]

  • Hemoglobinopathy

    RESULTS: Total HbA2 imprecision was 3.26% and 3.14% for normal and elevated HbA2 controls and 5.16% and 3.58% for a normal and a heterozygous HbS patient sample, respectively[ncbi.nlm.nih.gov] BACKGROUND: Diagnosis of hemoglobin (Hb) disorders is based mostly on abnormal red blood cell (RBC) indices, elevated levels of HbA2, HbF, or any other Hb on the Variant high[ncbi.nlm.nih.gov]

  • Megaloblastic Anaemia in Pregnancy

    One should offer to test the partner of any carrier of sickle hemoglobinopathies and any patient with elevated ( 3.5%) HbA2 to assess the risk to the fetus.[emedicine.medscape.com]

  • Thalassemia

    Conclusions: The elevated HbA2 5.3% is a useful marker for initial discrimination between homozygous HbE with and without α0-thalassemia trait.[ncbi.nlm.nih.gov] Electrophoresis demonstrates slightly diminished HbA1, elevated HbA2 and and normal HbF. Of the following, which is the most appropriate next step in management?[medbullets.com] The hemoglobin electrophoresis with beta thalassemia trait usually has reduced or absent HbA, elevated levels of HbA2, and increased HbF. 2 However, a normal concentration[aafp.org]

  • Thalassemia Minor

    Electrophoresis demonstrates slightly diminished HbA1, elevated HbA2 and and normal HbF. Of the following, which is the most appropriate next step in management?[medbullets.com] -An elevated concentrations of a normal hemoglobin called HbA2 could be detected. 1, 2 -Detecting the thalassemia gene by PCR : In which we are searching for the previously[cure2children.org] […] count, decreased HbA2.[wardelab.com]

  • Beta Thalassemia

    Electrophoresis demonstrates slightly diminished HbA1, elevated HbA2 and and normal HbF. Of the following, which is the most appropriate next step in management?[medbullets.com] HbF in such individuals is consistently elevated, varying from 5% to 20%.[ncbi.nlm.nih.gov] The hemoglobin electrophoresis with beta thalassemia trait usually has reduced or absent HbA, elevated levels of HbA2, and increased HbF. 2 However, a normal concentration[aafp.org]

  • Cooley's Anemia

    Elevated HbA2 on electrophoresis or column chromatography is diagnostic of the beta thalassemia trait.[symptoma.com] The hemoglobin electrophoresis with beta thalassemia trait usually has reduced or absent HbA, elevated levels of HbA2, and increased HbF. 2 However, a normal concentration[aafp.org] Normal HbA 2 is between 1.5 and 3.0% whilst HbA2 3.5 % is diagnostic. DNA testing is only available in specialised laboratories.[patient.info]

  • Thalassaemia-Haemoglobin C Disease

    S beta -thal Double Heterozygote: HbS and beta plus-thalassemia HbS: always dominates, typically 60-80% HbA1: 15-30% HbA2: elevated to 3-8% HbF: 2-20%, higher for age in infants[medicalgeek.com] The presence of HbS elevates the measurement of HbA2 when high-pressure liquid chromatography (HPLC) is used to measure it.[wardelab.com] S betao-thal Double Heterozygote: HbS and beta null thalassemia HbS: 75-90% HbA1: absent unless transfused HbA2: 5-8% HbF: 5-20% in adults, higher for age in infants 4.[medicalgeek.com]
