Kev faib tawm ntawm cov ntshav coagulation feem ntau suav nrog lub sijhawm plasma prothrombin (PT), lub sijhawm ua haujlwm ib nrab prothrombin (APTT), fibrinogen (FIB), lub sijhawm thrombin (TT), D-dimer (DD), qhov sib piv thoob ntiaj teb (INR).

PT: Nws feem ntau qhia txog qhov xwm txheej ntawm lub cev coagulation system, uas INR feem ntau siv los saib xyuas cov tshuaj anticoagulants hauv qhov ncauj. Kev ncua sijhawm pom tau hauv cov neeg mob uas muaj congenital coagulation factor ⅡⅤⅦⅩ deficiency thiab fibrinogen deficiency, thiab cov neeg mob uas tau txais coagulation factor deficiency feem ntau pom hauv cov neeg mob uas tsis muaj vitamin K deficiency, kab mob siab hnyav, hyperfibrinolysis, DIC, cov tshuaj anticoagulants hauv qhov ncauj, thiab lwm yam; kev luv luv pom tau hauv cov ntshav hypercoagulable thiab kab mob thrombosis, thiab lwm yam.

APTT: Nws feem ntau qhia txog qhov xwm txheej ntawm lub cev coagulation endogenous, thiab feem ntau siv los saib xyuas qhov koob tshuaj ntawm heparin. Kev nce hauv plasma factor VIII, factor IX thiab factor XI txo cov qib: xws li hemophilia A, hemophilia B thiab factor XI tsis txaus; txo qis hauv hypercoagulable state: xws li kev nkag mus ntawm cov tshuaj procoagulant rau hauv cov ntshav thiab kev ua haujlwm ntawm cov coagulation factors, thiab lwm yam.

FIB: feem ntau yog qhia txog cov ntsiab lus ntawm fibrinogen. Nce hauv kev mob plawv nres thiab txo qis hauv DIC consumptive hypocoagulable dissolution period, primary fibrinolysis, mob siab hnyav, thiab mob siab cirrhosis.

TT: Nws feem ntau yog qhia txog lub sijhawm uas fibrinogen hloov mus ua fibrin. Qhov nce ntxiv tau pom nyob rau theem hyperfibrinolysis ntawm DIC, nrog rau qis (tsis muaj) fibrinogenemia, tsis zoo hemoglobinemia, thiab nce fibrin (fibrinogen) degradation products (FDP) hauv cov ntshav; qhov txo qis tsis muaj qhov tseem ceeb hauv kev kho mob.

INR: Tus lej International Normalized Ratio (INR) yog xam los ntawm lub sijhawm prothrombin (PT) thiab International Sensitivity Index (ISI) ntawm cov tshuaj ntsuam xyuas. Kev siv INR ua rau PT ntsuas los ntawm ntau lub chaw soj nstuam thiab ntau cov tshuaj ntsuam sib piv, uas ua rau kev sib koom ua ke ntawm cov qauv tshuaj.

Qhov tseem ceeb tshaj plaws ntawm kev kuaj ntshav coagulation rau cov neeg mob yog xyuas seb puas muaj teeb meem nrog cov ntshav, kom cov kws kho mob tuaj yeem nkag siab txog tus neeg mob tus mob raws sijhawm, thiab nws yooj yim rau cov kws kho mob noj tshuaj thiab kev kho mob kom raug. Hnub zoo tshaj plaws rau tus neeg mob ua tsib qhov kev kuaj ntshav coagulation yog thaum lub plab khoob, kom cov txiaj ntsig ntawm kev kuaj yuav raug dua. Tom qab kev kuaj, tus neeg mob yuav tsum qhia cov txiaj ntsig ntawm kev kuaj rau tus kws kho mob kom paub txog cov teeb meem ntawm cov ntshav thiab tiv thaiv ntau yam xwm txheej.
