  • 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.

Q10. Life spane of RBC is 120 days

Ans.

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

Q11. What is the meaning of PT INR

Ans.

PT INR stands for Prothrombin Time International Normalized Ratio, a test used to measure how long it takes for blood to clot.

  • PT INR is a test used to monitor the effectiveness of blood-thinning medications like warfarin.

  • It is calculated by dividing the patient's PT by the average PT of a healthy population, raised to the power of the International Sensitivity Index (ISI).

  • A normal PT INR value is typically between 2.0 and 3.0, but this range may vary depending on the reason f...read more

Q12. Normal fasting levels.

Ans.

Normal fasting levels refer to the range of blood glucose levels after an overnight fast.

  • Normal fasting blood glucose levels range from 70-99 mg/dL
