La sedimentation tus nqi yog ib qho kev xeem uas ntsuas qhov sedimentation tus nqi, los yog dawb poob ntawm cov qe ntshav liab (cov ntshav liab) nyob rau hauv cov ntshav coj mus rau hauv ib lub raj upright tom qab ib teev.

Qhov ceev no nyob ntawm qhov concentration ntawm protein hauv cov ntshav. Nws txawv tshwj xeeb hauv qhov xwm txheej ntawmo, thaum cov qib ntawm inflammatory proteins, fibrinogen los yog immunoglobulins nce. Nws yog yog li ntawd feem ntau yog siv los ua tus cim ntawm o.

Qhov kev xeem no feem ntau raug txiav txim rau tib lub sijhawm raws li qhovhemogram duab (los yog ntshav suav). Nws tau nce ntxiv los ntawm kev ntsuas xws li ntsuas ntawm CRP lossis procalcitonin, uas tso cai rau kev kuaj mob ntau dua.

Tus nqi sedimentation tuaj yeem suav tau hauv ntau qhov xwm txheej, tshwj xeeb rau:

• nrhiav qhov mob
• ntsuam xyuas qib ntawm kev ua haujlwm ntawm qee yam kab mob rheumatic xws li mob caj dab rheumatoid
• kuaj pom qhov txawv txav ntawm immunoglobulins (hypergammaglobulinemia, monoclonal gammopathy)
• saib xyuas kev nce qib lossis kuaj pom myeloma
• nyob rau hauv cov ntaub ntawv ntawm nephrotic syndrome los yog lub raum tsis ua hauj lwm

Qhov kev sim no yog nrawm, pheej yig tab sis tsis meej heev thiab nws yuav tsum tsis txhob raug qhia hauv kev kuaj ntshav, raws li cov lus pom zoo ntawm Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv hauv Fab Kis.

Kev ntsuam xyuas yog ua raws li cov qauv ntshav yooj yim, uas zoo dua ua rau ntawm lub plab khoob. Tus nqi sedimentation yuav tsum tau nyeem ib teev tom qab sau.

Qhov tshwm sim yog qhia hauv millimeters tom qab ib teev. Tus nqi sedimentation txawv ntawm poj niam txiv neej (ntau dua ntawm cov poj niam dua li txiv neej) thiab hnub nyoog (ntau dua hauv cov neeg laus dua li cov hluas). Nws kuj nce ntxiv thaum cev xeeb tub thiab thaum noj qee yam tshuaj estrogen-progestogen.

Tom qab ib teev, feem ntau, qhov tshwm sim yuav tsum tsawg dua 15 lossis 20 hli hauv cov neeg mob hluas. Tom qab 65 xyoo, nws feem ntau tsawg dua 30 lossis 35 hli nyob ntawm kev sib deev.

Peb kuj tuaj yeem muaj qhov kwv yees ntawm cov txiaj ntsig ib txwm muaj, uas yuav tsum nyob qis dua:

- rau txiv neej: VS = hnub nyoog hauv xyoo / 2

- rau poj niam: VS = hnub nyoog (+10) / 2

Thaum tus nqi sedimentation nce siab heev (kwv yees li 100 hli ib teev), tus neeg yuav raug kev txom nyem:

• tus kab mob,
• malignant qog los yog ntau yam myeloma,
• mob raum mob,
• kab mob inflammatory.

Lwm yam mob uas tsis yog mob xws li ntshav ntshav lossis hypergammaglobulinemia (piv txwv li tshwm sim los ntawm HIV lossis kab mob siab C) kuj tuaj yeem nce ESR.

Ntawm qhov tsis sib xws, qhov txo qis hauv sedimentation tuaj yeem pom nyob rau hauv rooj plaub ntawm:

• hemolysis (kev puas tsuaj txawv txav ntawm cov qe ntshav liab)
• hypofibrinemia (poob hauv qib fibrinogen),
• hypogammaglobulinemia,
• polycythemia (uas tiv thaiv sedimentation)
• noj qee yam tshuaj tiv thaiv kab mob hauv cov koob tshuaj ntau
• thiab lwm yam

Nyob rau hauv cov ntaub ntawv uas tus nqi sedimentation yog nruab nrab, piv txwv li ntawm 20 thiab 40 mm / h, qhov kev ntsuam xyuas yog tsis heev tshwj xeeb, nws yog ib qhov nyuaj rau paub meej tias qhov muaj mob. Lwm yam kev sim xws li CRP thiab kev kuaj fibrinogen tej zaum yuav tsim nyog.
