Question 1

Why does ESR increase during pregnancy?

Accepted Answer

This is a physiological norm due to changes in the protein composition of the blood and an increase in plasma volume.

Question 2

Can ESR be high without illness?

Accepted Answer

Yes, during menstruation, after vaccination or in older people (after 60 years, up to 20–30 mm/h is acceptable).

Question 3

How to prepare for the analysis?

Accepted Answer

Donate blood in the morning on an empty stomach. Avoid fatty foods and alcohol the day before the test.

Question 4

How does ESR differ from CRP?

Accepted Answer

The ESR reacts more slowly (after 24–48 hours), but lasts longer. CRP is a more sensitive marker of acute inflammation.
