ACC Interview Questions and Answers

The blood will turn brownish yellow after adding n/10 HCl.

• n/10 HCl is a dilute hydrochloric acid solution

• The acid helps to break down the blood cells and release hemoglobin

• The color change is due to the formation of acid hematin

• The test is used to detect the presence of blood in a sample

Yes, serum is the clear, yellowish fluid that remains after blood has clotted.

• Serum is obtained by allowing the blood to clot and then removing the clot and the blood cells.

• It contains various proteins, electrolytes, hormones, and antibodies.

• Serum is used in various diagnostic tests to detect the presence of certain substances in the blood.

• Examples of tests that use serum include liver function tests, lipid profile, and hormone assays.

The lifespan of red blood cells (RBCs) is approximately 120 days.

• Red blood cells have a finite lifespan and are constantly being replaced by new cells.

• The average lifespan of RBCs is around 120 days, but it can vary slightly between individuals.

• After 120 days, old and damaged RBCs are removed from circulation by the spleen and liver.

• The production of new RBCs occurs in the bone marrow to maintain a constant supply.

• Certain medical conditions or disorders can affect the lifespa...read more

• Serum is the liquid part of blood that does not contain cells or clotting factors.

• It contains electrolytes, hormones, antibodies, and other proteins.

• Serum is used in medical testing to diagnose diseases and monitor treatment.

• Examples of serum tests include electrolyte panel, liver function tests, and lipid panel.

• Serum can also be used in research to study biomarkers and dise...read more

The lifespan of RBCs is approximately 120 days.

• RBCs are constantly being produced and destroyed in the body

• The average lifespan of RBCs is determined by the rate of production and destruction

• Factors such as age, health, and medical conditions can affect RBC lifespan

• RBCs are removed from circulation by the spleen and liver

• New RBCs are produced in the bone marrow

There are four types of hemoglobin: oxy, carboxy, met, and sulfhemoglobin.

• Oxyhemoglobin is formed when oxygen binds to hemoglobin in the lungs.

• Carboxyhemoglobin is formed when carbon monoxide binds to hemoglobin, which can be toxic.

• Methemoglobin is formed when iron in hemoglobin is oxidized, making it unable to bind to oxygen.

• Sulfhemoglobin is formed when sulfur binds to hemoglobin, which can cause a decrease in oxygen transport.
