[ad_1] Bloodborne pathogens are agents of diseases found in blood and bodily fluids, such as HIV, hepatitis B and C, malaria, and syphilis. Medical professionals use measures to reduce transmission, and strict protocols are followed in hospitals. Some biologists study bloodborne pathogens for treatment techniques. Bloodborne pathogens are agents of diseases such as viruses that […]
[ad_1] Coughing up blood, or hemoptysis, can be caused by various medical conditions. In healthy individuals, it is usually a symptom of a mild bronchial infection, while in smokers, it could signal a more serious condition such as lung cancer.

[ad_1] Blood tests can help diagnose medical conditions such as anemia, leukemia, and bacterial infections. A complete blood count measures red and white blood cell counts, hemoglobin, platelets, and hematocrit levels. A chemistry panel can detect liver, kidney, or thyroid gland problems, electrolyte imbalances, and pancreatic problems. Other blood panels may be prescribed for specific […]
[ad_1] Blood in sputum can indicate lung or heart problems. Pneumonia, bronchitis, and tuberculosis can cause bloody sputum. Congestive heart failure can also cause this symptom. Treatment depends on accurate diagnosis and may involve medication, rest, and lifestyle changes. Blood in sputum, known medically as hemoptysis, is a term used when a person spits up […]
[ad_1] Nosebleeds, or epistaxis, can be caused by the rupture of blood vessels in the nasal septum. High blood pressure and anticoagulant medications can increase the risk of nosebleeds. Remedies include applying an ice pack and pinching the nose, but severe cases may require external pressure or cauterization. Nosebleeds are known in medical terms as […]
[ad_1] Blood sugar levels rise after eating, with highly refined carbs causing a sudden spike. Portable blood glucose meters can test levels, which should not exceed 100 mg/dL two hours after eating. Diabetes can be managed with diet, exercise, and insulin. Consult a doctor for concerns. There is normally a rise in blood sugar after […]
[ad_1] Humans evolved different blood types in response to disease. The ABO system distinguishes four blood types, but there are actually 29 different blood group systems with over 600 distinct antigens. Type O is the universal donor, while type AB is the universal recipient. The Rhesus blood group system is often integrated with the ABO […]
[ad_1] Blood screening tests for diseases and conditions such as HIV, pregnancy, blood type, infections, and cancer. Patients visit a doctor’s office or hospital to have blood drawn, and results can be affected by contaminated utensils. Second tests are often used for accuracy.

[ad_1] The fecal occult blood test detects hidden blood in stool and can indicate early signs of colorectal cancer. It is easy to do at home with a kit provided by a doctor, but false positives can occur from certain foods and medications. It is recommended for individuals over 50 to have an annual screening. […]
[ad_1] Insulin regulates blood sugar levels by helping cells use glucose for energy. Malfunctions in this system occur in diabetes, causing potentially dangerous blood sugar levels. High sugar/carb foods cause excess blood sugar, triggering extra insulin release. Diabetes requires careful monitoring and treatment. There is a direct connection between insulin and blood sugar. Insulin is […]
[ad_1] Blood tests are used to diagnose celiac disease, an autoimmune and digestive disorder caused by gluten. The celiac blood panel shows higher levels of certain antibodies, which are used in conjunction with clinical symptoms and a biopsy to diagnose the disease. A gluten-free diet is the only treatment.
