【TSEEM CEEB】

Procalcitonin (PCT) yog ib qho protein me me uas muaj 116 amino acid residues nrog qhov hnyav molecular ntawm kwv yees li 13 kDa uas tau piav qhia thawj zaug los ntawm Moullec li al. Nyob rau hauv 1984. PCT yog tsim nyob rau hauv C-hlwb ntawm cov thyroid caj pas. Hauv xyoo 1993, qib siab ntawm PCT hauv cov neeg mob uas muaj kab mob ntawm cov kab mob hauv paus chiv keeb tau tshaj tawm thiab PCT tam sim no suav tias yog tus cim tseem ceeb ntawm kev tsis sib haum xeeb nrog rau cov kab mob hauv lub cev thiab sepsis. Tus nqi kuaj mob ntawm PCT yog qhov tseem ceeb vim muaj kev sib raug zoo ntawm PCT concentration thiab qhov mob hnyav. Nws tau pom tias "inflammatory" PCT tsis tsim nyob rau hauv C-hlwb. Cov hlwb ntawm cov keeb kwm neuroendocrine yog suav tias yog lub hauv paus ntawm PCT thaum mob.

【LUS QHIA RAU SIV】

Tso cai rau cov ntawv xeem, cov qauv, tsis thiab / lossis kev tswj kom sib npaug ntawm chav sov (15 - 30 ℃) ua ntej kuaj.

1. Tshem cov Test Cassette ntawm lub hnab ntawv thiab siv nws sai li sai tau. Cov txiaj ntsig zoo tshaj plaws yuav tau txais yog tias qhov ntsuas tau ua tiav hauv ib teev.

2. Muab Test Cassette rau ntawm qhov chaw huv si thiab theem.

Rau cov ntshav los yog Plasma cov qauv:

Tuav lub dropper vertically thiab hloov 1 poob ntawm cov ntshav los yog ntshav (kwv yees li 25μL) rau cov qauv zoo (S) ntawm Test Cassette, thiab ntxiv 1 tee ntawm tsis muaj (kwv yees li 40μL), ces pib lub sijhawm. Saib daim duab hauv qab no.

Rau Venipuncture Whole Blood specimens:

Tuav lub dropper vertically thiab hloov 2 tee ntawm cov ntshav tag nrho (kwv yees li 50μL) mus rau cov qauv zoo (S) ntawm Test Cassette, thiab ntxiv 1 poob ntawm qhov tsis muaj (kwv yees li 40μL), ces pib lub sijhawm. Saib daim duab hauv qab no.

Rau Fingerstick Whole Blood specimens:

Txhawm rau siv lub raj capillary: Sau lub raj capillary thiab hloov mus rau kwv yees li 50μL ntawm tus ntiv tes ntiv tes tag nrho cov ntshav mus rau qhov hnoos qeev (S) ntawm Test Cassette, tom qab ntawd ntxiv 1 poob ntawm qhov tsis txaus (kwv yees li 40μL) thiab pib lub sijhawm. Saib daim duab hauv qab no.

3. Tos kom pom cov xim muaj xim. Cov txiaj ntsig yuav tsum tau nyeem ntawm 15 feeb. Tsis txhob txhais cov txiaj ntsig tom qab 20 feeb.
