Sed Rate in THR:

Sed Rate: Osteomyelitis of the Spine:
- Discussion:
- measurement of the increased rate of settling of erythrocytes is an important laboratory test in evaluation of
disease activity in patients with connective-tissue diseases, certain infections, and neoplastic diseases;
- a useful measure to follow the course of previously diagnosed specific illnesses;
- westergren method;
- normal values are 0-9 mm per hour for men & 0-20 mm/hr for women;
- conditions which increase sed rate:
-
infection
- inflammatory conditions
- cancer (
lymphoma,
multiple myeloma)
- pregnancy (third month to 1-month post partum);
- surgery:
- in routine orthopaedic procedures maximum of 25 to 100 mm / hour is reached at 4 days, which gradually decreases to nl over 1-2 weeks;
- w/ more extensive surgery (THR) mild elevation may perist for upto one year;
- heparinized blood;
- conditions that decrease the sed rate:
- rate may be "falsely low" in conditions in which red blood cells do not undergo rouleaux formation;
-
sickle cell anemia
- hereditary spherocytosis;
- cold agglutinin disease;
- cachexia;
