挺重要的，難得有臨床也用的到的題目，務必背熟:
關節液判讀: 1. 有沒有血? 2. WBC數量(切2000) 3.PMN(切75%) 4. WBC>50000-> septic arthritis

附上卡片
synovial joint fluid:
1. {{c2::blood}}? yes- {{c1::truama}}, {{c1::coag}} problem, {{c1::neuropathic arthropathy}}({{c1::charcot}} joint)
2. {{c2::WBC}} count- <{{c3::2000}}: {{c4::non inflammatory}}({{c4::OA}}), >{{c3::2000}}: look for {{c5::PMN}}
3. {{c2::PMN}}<{{c3::75}}%: {{c4::non inflammatory}}({{c4::OA}}), >{{c3::75}}%: {{c5::inflammatory}}-> ({{c5::septic}} arthritis or {{c5::crystal}} induced arthritis)
1. {{c2::blood}}? yes- {{c1::truama}}, {{c1::coag}} problem, {{c1::neuropathic arthropathy}}({{c1::charcot}} joint)
2. {{c2::WBC}} count- <{{c3::2000}}: {{c4::non inflammatory}}({{c4::OA}}), >{{c3::2000}}: look for {{c5::PMN}}

順便補充: 關節液抽吸的indication:
- monoarthritis
- truama
- 有感染現象
