The Hemoglobin Test measures the amount of hemoglobin in blood, the protein that carries oxygen to tissues. Low hemoglobin may indicate anemia, blood loss, or nutritional deficiencies, while high levels may suggest dehydration, lung disease, or bone marrow disorders. Doctors order this test to evaluate fatigue, weakness, or shortness of breath. Results provide key insight into oxygen transport, red blood cell health, and overall hematologic function.
The Hemoglobin and Hematocrit Test measures hemoglobin levels and the percentage of red blood cells in blood to assess oxygen-carrying capacity. Low values may indicate anemia, blood loss, or nutritional deficiencies, while high levels may suggest dehydration, lung disease, or polycythemia. Doctors use this test to investigate fatigue, weakness, or shortness of breath. Results provide vital insight into red blood cell health, oxygen delivery, and overall hematologic function.
The Hemoglobin Free Urine Test measures the presence of free hemoglobin in urine, which may indicate intravascular hemolysis or red blood cell destruction. Detecting hemoglobinuria helps evaluate kidney filtration, hemolytic anemia, and related conditions. This test aids in identifying underlying causes of hemolysis, such as transfusion reactions, infections, or mechanical red cell damage.
The Unstable Hemoglobin Test detects abnormal hemoglobin variants prone to instability and breakdown, which can cause hemolytic anemia. Unstable hemoglobins may lead to premature red blood cell destruction, anemia, jaundice, or splenomegaly. This test helps identify hereditary hemoglobin disorders, supports differential diagnosis of unexplained hemolysis, and provides insight into genetic causes of red cell fragility.
The Hemoglobinopathy Evaluation screens for abnormal hemoglobin variants and thalassemias by analyzing the types and amounts of hemoglobin in blood. This test helps diagnose sickle cell disease, beta thalassemia, alpha thalassemia, and other inherited disorders affecting red blood cells. Doctors use it to investigate anemia, unexplained blood abnormalities, or family history of hemoglobinopathies, guiding diagnosis, genetic counseling, and treatment planning.

The Hemoglobin A1c (HbA1c) Test measures average blood glucose over 2–3 months by detecting sugar attached to hemoglobin in red blood cells. It is used to diagnose diabetes, identify prediabetes, and monitor long-term blood sugar control. Doctors rely on the HbA1c test to evaluate treatment effectiveness, guide adjustments, and assess risk for complications, making it essential for diabetes care and metabolic health screening.
The Hemoglobin A1c with eAG Test measures average blood sugar levels over the past 2–3 months and provides an estimated average glucose (eAG) value for easier understanding. It is widely used to screen, diagnose, and monitor diabetes and prediabetes. Doctors use this test to evaluate long-term glucose control, adjust treatment, and reduce the risk of complications such as neuropathy, kidney disease, and heart problems linked to poor blood sugar management.
The Hemoglobin A1c (HbA1c) test measures the average blood glucose level over the past two to three months. It provides valuable information about long-term blood sugar control in individuals with diabetes.
The Hemoglobin A1c with Calculated Mean Plasma Glucose Test measures average blood sugar over 2–3 months and provides an estimated mean plasma glucose (eAG). Elevated A1c may indicate diabetes or poor glucose control, while normal results reflect healthy management. Doctors use this test to diagnose diabetes, assess long-term control, and adjust treatment. Results give valuable insight into glycemic control, reducing risk of complications like kidney, eye, and heart disease.
The Haptoglobin Test measures levels of haptoglobin, a protein produced by the liver that binds free hemoglobin released from red blood cells. Low levels may indicate hemolytic anemia, liver disease, or red blood cell destruction, while elevated levels may occur with inflammation or tissue damage. Doctors use this blood test to help diagnose anemia causes, assess liver function, and monitor conditions affecting red blood cell health.
The Sickle Cell Screen detects abnormal hemoglobin S in blood to identify sickle cell trait or sickle cell disease. A positive screen suggests the presence of sickle hemoglobin, which may require confirmatory testing. Doctors order this test for newborn screening, genetic counseling, or evaluating anemia, pain crises, or family history of hemoglobin disorders. Results provide key insight into sickle cell status, red blood cell health, and hereditary blood conditions.
