also know as joint fluid
a. synovial fluid
b. serous fluid
c. amniotic fluid
synovial fluid
this fluid formed as a non selective ultrafiltrate of plasma
a. synovial fluid
b. serous fluid
c. amniotic fluid
synovial fluid
- formed as a non selective ultrafiltrate of plasma across the synovial membrane except for the exclusion of high molecular weight
responsible for the viscosity of synovial fluid
a. albumin
b. proteins
c. hyaluronic acid
hyaluronic acid
functions of synovial fluid, except:
a. to provide lubrication between 2 membranes as the surface move to each other
b. lubricates the joint
c. reduce the friction between bones
d. provides nutrients to the articular cartilage
FUNCTIONS OF SYNOVIAL FLUID
- LUBRICATES THE JOINT
- REDUCE THE FRICTION BETWEEN BONES
- PROVIDES NUTURIENTS TO THE ARTICULAR CARTILAGE
- LESSEN THE SHOCK OF JOINTY COMPRESSION OCCURING DURING ACTIVITIES
ANS: A
in synovial fluid, if possible the patient should be on fasting for how many hours
a. 8-12 hours
b. 6-8 hours
c. 4-6 hours
if possible the patient should be on fasting for 4 to 6 hours to allow for the equilibration of chemical constituents between plasma and synovial fluid
order of distribution
in what order of tube to send in hematology
a. 1st
b. 2nd
c. 3rd
d. 4th
collection tube disorder on SYNOVIAL FLUID
1st - chemistry and serology
2nd - hematology and cytology
3rd - microbiology
CHeM
what kind of edta to be used in hematology on synovial fluid
a. liquid form
b. dry form
liquid form
synovial fluid : volume for inflammation
a. 0.1 to 3.5 ml
b. >15 ml
c. >25ml
normal: 0.1 to 3.5 ml
inflammation: >25ml
test for the viscosity of synovial fluid
a. toluidine blue
b. ropes / mucin clot test
c. catalase
rope or mucin clot test ( hyaluronate polymerization test)
reagent: 2- 5 % of acetic acid
friable clot what grading it is in rope/ mucin clot
a. good
b. fair
c. low
low
good - solid clot
fair - soft
low - friable clot
poor - no clot
normal color of synovial fluid
a. colorless to pale yellow
b. deeper yellow
c. greenish inge
d. milky
colorless to pale yellow - normal
turbid - wbc, synovial cell debris, fibrin
deeper yellow - inflammation
greenish tinge - bacterial infection
red - traumatic tap , hemorrhagic arthritis
milky - crystals
promotes clot in synovial fluid
a. hyaluronic acid
b. acetic acid
c. toluidine blue
acetic acid
most predominant wbc cells can be found on a normal synovial fluid
a. monocyte
b. neutrophil
c. lymphocyte
d. macrophages
monocytes and macrophages - 65%
neutrophil - 25%
lymphocytes - 15%
similar to macrophage, but may be multinucleated resembling a mesothelial cell
a. LE cells
b. synovial lining cell
c. RA cell
d. reiter cell
synovial lining cell
description : similar to macrophage, but may be multinucleated resembling a mesothelial cell
significance : normal
neutrophil containig characteristics ingested
“ ROUND HOMOGENOUS BODY “
a. LE cells
b. synovial lining cell
c. RA cell
d. reiter cell
LE cell
round homogenous body
significance : lupus eryrhematous
