Question

If you suspect a major deficiency of antibodies in a person, to which of the following would you look for confirmatory evidence?

• A. Serum globulins
• B. Fibrinogen in plasma
• C. Serum albumins
• D. Haemocytes

Answer 1

The correct option is A

Serum globulins

The correct option is A.

Explanation of the correct option:

1. Our immune system creates defensive proteins called antibodies.
2. They bind to foreign substances known as antigens, including bacteria, fungi, viruses, and poisons, and expel them from our bodies.
3. The immune system uses antibodies, often referred to as immunoglobulins, to recognize and destroy foreign substances including harmful bacteria and viruses.
4. The antigen, or distinctive molecule of the infection, is recognized by the antibody.
5. The serum globulin electrophoresis test quantifies the concentrations of fluid-soluble proteins known as globulins in a blood sample.
6. The name of this liquid is serum.
7. Venipuncture, the act of drawing blood from a vein, is frequently performed on the inside of the elbow or the back of the hand.

Explanation of the incorrect options:

Option B:

1. The primary plasma protein coagulation factor is fibrinogen.
2. Consequently, low plasma fibrinogen concentrations are linked to a higher risk of bleeding because they impede primary and secondary hemostasis.
3. Because of its connection to pulmonary function, plasma fibrinogen is regarded as a biomarker of respiratory illness.

Option C:

1. Serum albumin, often known as blood albumin or just serum, is albumin that is present in the blood of vertebrates.
2. The ALB gene produces human serum albumin.
3. Bovine serum albumin and other mammalian versions are chemically related.
4. The serum albumin test examines a person's blood albumin levels.
5. If the results show an excessive amount of albumin, the liver or kidneys may be the culprits.
6. One of the most prevalent proteins in blood is albumin.

Option D:

1. An invertebrate's immune system contains cells called hemocytes.
2. It can be discovered in the hemolymph.
3. Invertebrate phagocytes include hemocytes.
4. Similar to vertebrate macrophages, insect hemocytes serve essential effector and effector functions in insect immunology.

Final answer: If we suspect a major deficiency of antibodies in a person, we will look for serum globulins for confirmatory evidence.
