Respiratory Syncytial Virus Rapid Test

Npaj siv

Respiratory Syncytial Virus Rapid Test yog ib qho hauv vitro immunoassay rau kev kuaj pom ncaj qha thiab zoo ntawm tus kab mob ua pa syncytial (RSV) antigens los ntawm tib neeg qhov ntswg / nasopharyngeal swabs lossis qhov ntswg ntxuav / aspirates. Respiratory Syncytial Virus Rapid Test yog npaj los pab rau kev kuaj mob sai ntawm RSV. Cov txiaj ntsig tsis zoo tsis txwv tsis pub muaj tus kab mob RSV thiab yuav tsum tau lees paub los ntawm kab lis kev cai kab lis kev cai lossis kev tshuaj ntsuam molecular. RSV Antigen Rapid Test Device yog rau kev siv xwb.

Taw qhia

RSV yog ib tus kab mob RNA tsis zoo ntawm tsev neeg Paramyxoviridae 1. Nws yog tus kab mob ua rau tus kab mob kis tau zoo heev, mob hnyav, kis kab mob ntawm lub ntsws. Thoob plaws ntiaj teb, RSV ua rau muaj kev tuag txog li 1,000,000 cov me nyuam mos thiab cov me nyuam hnub nyoog qis dua tsib xyoos txhua xyoo2. Nws kuj yog tus kab mob tseem ceeb ntawm cov kab mob nosocomial hauv cov menyuam yaus twb tau mus pw hauv tsev kho mob rau lwm yam laj thawj3. Ntawm cov menyuam yaus nyob hauv tsev kho mob nrog tus kab mob RSV, tus neeg tuag tau kwv yees tsawg li 0.3 feem pua ​​​​rau 1.{{10}} feem pua ​​4 thiab nyob rau hauv thaj tsam ntawm 2.5 feem pua ​​​​rau 4.0 feem pua. rau cov menyuam yaus uas muaj mob plawv lossis mob ntsws 5. Tus kab mob RSV tsuas yog txwv kev tiv thaiv kab mob xwb. Yog li ntawd, cov tib neeg tuaj yeem kis tus kab mob ntau ntxiv thiab tsim cov kab mob hnyav thoob plaws hauv lawv lub neej6.

RSV tsuas muaj ib qho serotype xwb, thiab muab faib ua ob pawg antigenic, A thiab B7. Ob pab pawg ncig ib txhij hauv zej zog. Subtype B yog tus cwj pwm raws li cov kab mob asymptomatic ntawm tus kab mob uas feem coob ntawm cov pej xeem ntsib. Cov kab mob hnyav dua muaj cov kab mob subtype A, uas zoo li ua rau muaj feem ntau ntawm cov kab mob. RSV tej zaum yuav xav tias raws li lub sij hawm ntawm lub xyoo ntawm tus kab mob; Feem ntau yog coincides nrog lub caij ntuj no khaub thuas.

RSV tuaj yeem kuaj hauv chav kuaj siv cov pa ua pa. rhiab heev ntawm kev cais tus kab mob los ntawm kev ua pa tawm hauv cov kab mob ntawm tes sib txawv ntawm cov chaw kuaj mob. Kev soj ntsuam siab RT-PCR yuav tsum tau txiav txim siab thaum kuaj cov neeg laus, vim tias lawv yuav muaj cov kab mob qis hauv lawv cov qauv ua pa. Txawm hais tias muaj txiaj ntsig zoo rau kev tshawb fawb, kev sim serologic tsis tshua siv rau kev kuaj mob. Seroconversion tsis tshwm sim tsawg kawg 2 lub lis piam thiab yuav xav tau 4 ~ 6 lub lis piam. Feem ntau cov chaw kuaj mob tam sim no siv cov tshuaj tiv thaiv antigen. Kev kuaj xyuas antigen thiab kab lis kev cai feem ntau txhim khu kev qha hauv cov menyuam yaus tab sis tsis tshua muaj txiaj ntsig rau cov menyuam yaus thiab cov neeg laus.

RSV Antigen Rapid Test Device yog ib qho yooj yim lateral flow immunoassay rau kev tshawb nrhiav ncaj qha ntawm RSV antigens. Nws yuav muab qhov kev kuaj pom zoo ntawm tus kab mob RSV.

Khoom siv

● Cov khoom siv kuaj tau ntim ib leeg

● Extraction raj

● Swb

● Ntim ntim

● RSV assay buffer

● Nozzle nrog lim

● Tube sawv

Cov txheej txheem xeem

Nqa cov khoom siv, cov tshuaj reagents thiab cov qauv thiab / lossis tswj rau hauv chav tsev kub (15 ~ 30 degree) ua ntej siv.

1. Rau txhua qhov hnoos qeev, qhib lub hnab ntawv ua ntej kuaj thiab tshem tawm cov cuab yeej kuaj, thiab muab tso rau ntawm qhov chaw huv, theem. Sau lub raj nrog tus neeg mob txheeb xyuas. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, qhov kev ntsuam xyuas yuav tsum tau ua hauv ib teev.

2. Maj mam sib tov qhov ntsuas tsis tau. Ntxiv 10 tee rau hauv lub raj rho tawm.

Rau Nasal / Nasopharyngeal Swabs

ib. Ntxig lub swab rau hauv lub raj extraction. Sib tov zoo thiab nyem lub swab ob peb zaug los ntawm compressing phab ntsa ntawm lub raj tiv thaiv lub swab.

b. Yob lub taub hau swab tawm tsam sab hauv ntawm lub raj thaum koj tshem nws. Sim tso kua ntau li ntau tau. Pov tseg cov swab siv raws li koj cov txheej txheem pov tseg biohazard pov tseg.

Rau Nasal Wash/Aspirate

ib. Vortex los yog ua tib zoo sib xyaw cov qauv. Tsis txhob centrifuge, vim tias kev tshem tawm ntawm cov khoom siv ntawm tes yuav ua rau muaj kev cuam tshuam rau kev sim siab.

b. Hloov 300 ul ntawm cov hnoos qeev mus rau hauv lub raj rho tawm siv hloov pipette.

3. Ntxig lim nozzle rau hauv cov qauv rho tawm raj. Hloov lub raj thiab ntxiv 2 tee (kwv yees li 100 uL) ntawm cov qauv kuaj rau hauv cov qauv zoo los ntawm maj mam muab lub raj.

4. Nyeem cov txiaj ntsig ntawm 15 feeb thiab tsis quav ntsej tom qab 20 feeb.
