Frequently ordered with glucose testing, the insulin test provides critical insight into endocrine health, blood sugar control, and risk for diabetes-related complications.

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.

The Lactate Dehydrogenase (LDH) Test measures LDH enzyme levels in blood to assess tissue damage and overall health. Elevated LDH may indicate conditions such as liver disease, heart attack, anemia, infections, or certain cancers, while low levels are uncommon. Doctors use this test to help diagnose disease, monitor treatment effectiveness, and track cell damage. It provides valuable insight into metabolic activity and organ function.

The Lead Blood Test measures lead levels in blood to detect exposure or poisoning. Even small amounts of lead can harm the nervous system, kidneys, and blood cells. High levels may cause developmental delays in children, fatigue, abdominal pain, or anemia in adults. Doctors use this test to monitor workplace exposure, environmental risks, or treatment effectiveness. Results provide essential insight into toxic exposure and long-term health protection.

The Lead Micronutrient Blood Test measures lead levels in the blood to assess exposure and potential toxicity. Lead, often found in contaminated water, soil, paint, or industrial settings, can harm the brain, nervous system, kidneys, and red blood cell production. This test helps detect harmful exposure, guide treatment, and monitor health risks related to lead accumulation.

Patient must be 18 years of age or older.

The Leptin Test measures leptin hormone levels in blood to evaluate metabolism, appetite regulation, and body fat balance. Abnormal levels may indicate obesity, metabolic syndrome, insulin resistance, or leptin deficiency. Doctors use this test to assess unexplained weight gain, difficulty losing weight, or potential endocrine disorders. It also supports research on energy balance, fertility, and overall metabolic health management.

The Lipase Test measures levels of lipase, an enzyme made by the pancreas that helps digest fats. Elevated lipase may indicate acute or chronic pancreatitis, pancreatic cancer, gallbladder disease, kidney failure, or bowel obstruction. Doctors order this test to investigate severe abdominal pain, nausea, or vomiting and to monitor pancreatic disorders. Results provide vital insight into digestive health, pancreatic function, and overall gastrointestinal balance.

The Lipid Panel Test checks six key blood lipids: total cholesterol, HDL cholesterol, LDL cholesterol, non-HDL cholesterol, triglycerides, and the Chol/HDL ratio. This panel assesses risk for cardiovascular disease, heart attack, and stroke by evaluating cholesterol balance and fat levels in the blood. Doctors use lipid panel results for routine screening, treatment monitoring, and guiding lifestyle or medication adjustments.

The Lipoprotein (a) Test measures Lp(a), a genetic form of LDL cholesterol linked to higher risk of heart disease, stroke, and atherosclerosis. Unlike standard cholesterol tests, Lp(a) levels are inherited and not easily lowered by lifestyle changes. Doctors order this test for patients with a family history of early cardiovascular disease or high cholesterol. Results help identify hidden risk, guide prevention strategies, and support heart and vascular health management.

The Magnesium Serum Test measures magnesium levels in blood to evaluate electrolyte balance, nerve and muscle function, and overall metabolic health. Abnormal levels may indicate kidney disease, malnutrition, gastrointestinal disorders, or uncontrolled diabetes. Low magnesium can cause weakness, cramps, or irregular heartbeat, while high levels may signal kidney dysfunction. Doctors use this test to diagnose deficiencies, monitor therapy, or assess chronic health conditions.

The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests.
