It is often ordered alongside tTG IgA and total IgA testing for accuracy.

Specimen Type: Serum

The Gliadin Deamidated Peptide IgG IgA Antibodies Test detects both IgG and IgA antibodies against deamidated gliadin peptides, highly specific markers for celiac disease. Elevated results indicate an autoimmune reaction to gluten that can damage the small intestine. Doctors use this test to confirm suspected celiac disease, evaluate unexplained digestive issues, or monitor compliance with a gluten-free diet, often alongside tTG and other celiac antibody tests.

Specimen Type: Serum

The Gliadin Deamidated Peptide IgG Antibody Test detects IgG antibodies to deamidated gliadin peptides, helping diagnose celiac disease in patients with IgA deficiency or gluten-related disorders. Elevated levels indicate an autoimmune response to gluten that may damage the small intestine. Doctors use this blood test to evaluate persistent digestive symptoms, confirm celiac disease, or monitor dietary compliance with a gluten-free diet for improved health outcomes.

Specimen Type: Serum

 A Glucagon test is a diagnostic examination used to measure the levels of glucagon, a hormone secreted by the alpha cells of the pancreas, in the blood. Glucagon plays a critical role in managing blood sugar levels by stimulating the liver to convert stored glycogen into glucose, which is then released into the bloodstream, thereby raising blood glucose levels. 

Specimen Type: Plasma-Unspecified Vial Pour

The Glucose Test measures blood sugar levels to evaluate energy metabolism and screen for diabetes or prediabetes. Abnormal glucose may indicate hyperglycemia, hypoglycemia, or metabolic disorders. Doctors use this test during routine exams, to investigate symptoms like fatigue, excessive thirst, or frequent urination, and to monitor treatment for diabetes. It provides essential insight into how the body regulates blood sugar and overall metabolic health.

Specimen Type: Serum

The Glucose-6-Phosphate Dehydrogenase (G6PD) Test measures enzyme activity to detect G6PD deficiency, a genetic condition that can lead to hemolytic anemia when exposed to certain foods, infections, or medications. Doctors order this test to assess unexplained anemia, jaundice, or family history of G6PD deficiency. Results help identify individuals at risk for red blood cell breakdown, guiding treatment, prevention, and safe medication use.

Specimen Type: Blood

The Glucose Plasma test, also known as a fasting blood sugar test, is a common laboratory test used to measure the concentration of glucose (sugar) in the blood. Glucose is the primary source of energy for the body's cells and is essential for normal bodily functions.

Specimen Type: Plasma-Unspecified Vial Pour

 The Glucose Random test is a blood test that measures the concentration of glucose in the bloodstream at any given time, regardless of when the individual last ate. It is different from the fasting glucose test, which requires an individual to abstain from eating for at least 8 hours prior to the test.

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.

Specimen Type: Serum

Specimen Type: Random

The Helicobacter pylori Antigen Stool Test detects H. pylori proteins in stool to diagnose active infection. H. pylori is a common cause of gastritis, ulcers, and increased stomach cancer risk. Doctors order this test for patients with abdominal pain, nausea, bloating, or indigestion. Noninvasive and accurate, results confirm active infection and are also used to monitor treatment effectiveness and eradication of H. pylori bacteria.

Specimen Type: Stool/Feces

The Helicobacter pylori Urea Breath Test detects H. pylori infection, a common cause of ulcers and gastritis. After drinking a urea solution, breath samples are analyzed for carbon dioxide changes caused by the bacteria. A positive result indicates active infection, while a negative shows no evidence of H. pylori. Doctors use this noninvasive test to diagnose infection, confirm eradication after treatment, and monitor gastrointestinal health.

Specimen Type: Varied

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.

Specimen Type: Blood

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.
