Ans to synovial fluid

Sorry for the late replying as I need to ask my colleagues.

Dorothy:

1.) Blood-stained synovial is hemorrhage. It bleeds into the joint, the blood is usually evenly distributed throughout the fluid. It is caused by traumatic tap. Any time bleeding occurs into the joint fluid, fibrinogen is introduced and will permit clot formation. In the event that fibrinogen is thought to be introduced, a tube containing sodium heparin should be available as part of the collection process. Non-clotted SyF is necessary for the microscopic examination.

2) In normal circumstances, the total protein of synovial fluid will be about 1/3 that of blood plasma. There are a variety of joint disorders that are characterized by elevated total protein levels (examples are rheumatoid and septic arthritis, crystal-induced synovitis, and hemorrhagic problems. It has been found that protein determinations of Synovial fluid does not assist in the differentiating of joint disorders, hence is not reliable. Protein determinations are usually not requested.

Ming Boon:

Traumatic tap is refer to bleeding into the subarachnoid space at the puncture site

For the differentiation of the exudate and transudate fluid is two type of category acording to the Light's criteria. Which i am trying to load the table. The table is the below:

Elaine:

Another limitation will be the fluid cell count must be done immediately as cell will broken down on prolong standing thus fluid must be examine as soon as possible.
