Gout is an inflammatory arthritis caused by deposits of monosodium urate crystals in and around joints. Hyperuricemia means that serum urate—often reported as “uric acid”—is elevated. The two are related, but they are not interchangeable: […]

Cardiovascular Health and Longevity at a Glance Cardiovascular health describes how effectively your heart and blood vessels deliver oxygen and nutrients throughout your body. It includes more than the absence of heart disease. Blood pressure, […]

High blood pressure, also called hypertension, increases the long-term risk of heart attack, stroke, heart failure, atrial fibrillation, kidney disease, and other complications. Because hypertension can affect several body systems without causing obvious symptoms, ongoing […]

Vitamin D tests do not all measure the same form of vitamin D. Learn which blood test is generally used to evaluate vitamin D status, when D2 and D3 fractions may add context, and why […]

A laboratory result usually answers a straightforward question: How much of a substance is present? A biomarker ratio asks a second question: How does that result relate to another part of the same biological system? […]

Obstructive sleep apnea, commonly called OSA, is a sleep-related breathing disorder in which the upper airway repeatedly narrows or closes during sleep. Each event may reduce airflow, lower blood oxygen, interrupt normal sleep, and activate […]

Inflammatory bowel disease, or IBD, is a group of chronic inflammatory conditions that includes Crohn’s disease and ulcerative colitis. Although diarrhea, abdominal pain, rectal bleeding, and bowel urgency are well-known warning signs, intestinal inflammation can […]

Vascular aging describes the gradual structural and functional changes that occur in the arteries over time. These changes may include increasing arterial stiffness, reduced elasticity, impaired function of the blood-vessel lining, chronic inflammation, and the […]

Rapid weight loss with medications such as semaglutide and tirzepatide can lead to meaningful changes in body weight, appetite, blood sugar, and cardiometabolic health. Semaglutide is a glucagon-like peptide-1 receptor agonist, commonly called a GLP-1 […]

Chronic kidney disease, commonly called CKD, occurs when the kidneys have a persistent structural or functional abnormality that affects health. CKD is not defined by one isolated blood test. Under current kidney guidelines, evidence of […]

Reducing belly fat is about more than changing how your waist looks. Fat stored deep inside the abdomen—known as visceral fat—surrounds internal organs and is associated with insulin resistance, abnormal cholesterol, fatty liver disease, inflammation, […]

Epstein-Barr virus blood tests measure antibodies—or, in specialized situations, viral genetic material—that can help determine whether someone has never been infected, may have a recent primary infection, or was infected in the past. Epstein-Barr virus, […]

The best diets for heart health are not short-term plans built around one “superfood” or a rigid list of forbidden ingredients. They are sustainable eating patterns that emphasize vegetables, fruits, whole grains, legumes, nuts, seeds, […]

Lipoprotein(a), usually written as Lp(a), is an inherited cholesterol-carrying particle that can increase the risk of atherosclerotic cardiovascular disease, heart attack, stroke, peripheral artery disease, and calcific aortic valve stenosis. Unlike LDL cholesterol and triglycerides, […]
