Question

что такое сыворотка крови?

Answer 1

Сыворотка крови-  плазма крови, лишённая фибриногена. Сыворотки получают либо путём естественного свёртывания плазмы (нативные сыворотки), либо осаждением фибриногена ионами кальция. В сыворотках сохранена большая часть антител, а за счёт отсутствия фибриногена резко увеличивается стабильность.

Сыворотку выделяют при анализе крови на инфекционные заболевания, при оценке эффективности вакцинации (титр антител), а также при биохимическом анализе крови.

Answer 2

СЫВОРОТКА КРОВИ, прозрачная желтоватая жидкость, отделяемая от кровяного сгустка после свертывания крови вне организма. Из сыворотки крови животных и людей, иммунизированных определенными антигенами, получают иммунные сыворотки, применяемые для диагностики, лечения и профилактики различных заболеваний. Введение сыворотки крови, содержащей чужеродные для организма белки, может вызывать проявления аллергии - боли в суставах, лихорадку, сыпь, зуд

What is Blood Serum?

Blood serum, also known as serum, is the clear, yellowish fluid that remains after blood has clotted and the blood cells have been removed. It is the liquid component of blood that is left behind when blood is allowed to clot and is commonly used in medical and scientific research. Serum contains various proteins, electrolytes, hormones, antibodies, and other substances that are important for the body's functioning.

Composition of Blood Serum

Blood serum is composed of a variety of components, including proteins, electrolytes, hormones, antibodies, and other substances. Here are some of the key components found in blood serum:

1. Proteins: Blood serum contains a wide range of proteins, including albumin, globulins, and fibrinogen. These proteins play important roles in maintaining osmotic pressure, transporting substances, and clotting blood.

2. Electrolytes: Electrolytes such as sodium, potassium, calcium, and magnesium are present in blood serum. These ions are essential for maintaining the body's pH balance, regulating fluid balance, and supporting nerve and muscle function.

3. Hormones: Blood serum contains various hormones, such as insulin, cortisol, and thyroid hormones. These hormones play crucial roles in regulating metabolism, growth, and other physiological processes.

4. Antibodies: Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to foreign substances (antigens). They help the body fight off infections and provide immunity against specific pathogens.

5. Other Substances: Blood serum also contains other substances like enzymes, waste products, vitamins, and nutrients that are necessary for the body's overall functioning.

Uses of Blood Serum

Blood serum has several important uses in medical and scientific fields. Here are a few examples:

1. Diagnostic Testing: Blood serum is commonly used in diagnostic tests to measure various substances in the body, such as glucose, cholesterol, liver enzymes, and kidney function markers. These tests can help diagnose and monitor various medical conditions.

2. Research and Studies: Blood serum is used in scientific research to study the composition of blood, identify biomarkers, and investigate disease mechanisms. It can provide valuable insights into the functioning of the body and help develop new treatments and therapies.

3. Blood Banking: Blood serum is used in blood banking to screen donated blood for infectious diseases and to match blood types for transfusions.

4. Drug Development: Blood serum is used in preclinical and clinical trials to evaluate the safety and efficacy of drugs. It can help determine how drugs are metabolized and distributed in the body.

In summary, blood serum is the clear, yellowish fluid that remains after blood has clotted and the blood cells have been removed. It contains proteins, electrolytes, hormones, antibodies, and other substances that are important for the body's functioning. Blood serum is used in various medical and scientific applications, including diagnostic testing, research, blood banking, and drug development
