Yuav ua li cas yog bilirubin, cai thiab sib txawv

Bilirubin - cov khoom neej puas hemoglobin. Nws yog txiav txim nyob rau hauv cov ntshiab thiab muab faib ua ncaj thiab indirect. Txoj kev tshawb fawb yog lub photometric calorimetry. Lub tsev ntawm kev ntsuas ntawm ncaj qha thiab indirect bilirubin yog micromoles ib liter. Biomaterials rau kev tsom xam tej zaum yuav venous los yog capillary ntshav. Ua ntej mus rau lub lab rau tus neeg mob yuav tsum tau 12 teev ua ntej lub caij tus tsom xam tsis tau zaub mov los yog ib tug 30-feeb pa luam yeeb.

Yuav ua li cas yog bilirubin? Nyob rau hauv lub laboratory, txiav txim ntau cov ntsiab lus ntawm bilirubin nyob rau hauv cov ntshav. Nws ua xim yellowish xim av thiab hniav zis, kua tsib thiab faeces coj xim.

Hemoglobin - ib feem ntawm ib tug liab ntshav cell. Nyob rau ua pa system hemoglobin thauj oxygen mus rau cov ntaub so ntswg, thiab nyob rau hauv kev coj rov qab - carbon dioxide. Raws li ib tug tshwm sim ntawm metabolic cleavage ntawm hemoglobin, uas yog tsim nyob rau ntawm indirect bilirubin (unconjugated). Thaum lub sij hawm lub hnub nws yog ua li 250 mg. Tom qab no ntxiv transformation tshwm sim nyob rau hauv lub siab. Hepatocytes khi bilirubin rau glucuronic acid, yog li, hloov ib conjugated (direct). Qhov no hom ntawm bilirubin yog tau yaj nyob rau hauv cov dej. Cov me me ntawm cov ntshav yog indirect xim. Thaum lub concentration ntawm metabolic mob yuav muab ntau zog, ua rau hyperbilirubinemia. High ntau qhia tej yam tshwm sim ntawm daj ntseg: daj ntawm daim tawv nqaij, txheej week thiab sclera, thiab kuj khaus.

Yuav ua li cas yog bilirubin? Peb hom mob ntawm bilirubin metabolism:

1. Hemolysis ntawm cov ntshav liab. Nws tshwm sim thaum muaj kev puas tsuaj ntawm cov ntshav liab. Nws cai nyob rau hauv sickle cell anemia, sverotsitoze, hemolytic kab mob ntawm cov me nyuam mos thiab cov zoo li Tsis tas li ntawd hemolysis zaum yuav tshwm sim raws li ib tug tshwm sim ntawm kis tau tus tej yam tshuaj lom nyob rau hauv lub cev.

2. Kev ua txhaum anatomical los yog tej qhov kev ncaj ncees ntawm lub hepatocytes. Ua ib lub xeev ntawm tus kab mob tus kab mob siab, raws li zoo raws li lub tshuaj lom nyhuv ntawm cawv, tshuaj, tsev neeg thiab cov muaj tshuaj.

3. Cov chaw khuam siab rau cov zaj uas lub kua tsib mus rau hauv cov hnyuv ntawm lub biliary ib ntsuj av. Nws tshwm sim thaum uas compressed los yog deformed txoj kev nyob rau hauv hlav, ua qog los yog dyskinesia.

Yuav ua li cas yog bilirubin? Analysis ntawm bilirubin pab kom paub tias ib tug xov tooj ntawm pathological tej yam kev mob uas ncaj qha los yog kov txuam nrog impaired siab los yog hematopoietic dab.

Tej tsom xam yog tsim nyog nyob rau hauv thiaj li yuav:

- mus kuaj ntau hom ntawm anemia;

- mus ntsuam xyuas kev ncaj ncees ntawm lub siab lub hlwb;

- txheeb xyuas kab mob kab mob siab;

- kom patency ntawm lub biliary ib ntsuj av tau;

- rau nrhiav kom tau ntawm hemolytic anemia ntawm me nyuam mos;

- qhia kom meej rau cov heev ntawm tus neeg mob tus mob sib txawv ntawm kev qaug tshuaj lom.

Yuav ua li cas yog bilirubin? Ua lub theem ntawd hais kev puas tsuaj ntawm cov ntshav liab, kev puas tsuaj rau lub hepatocyte los yog teeb meem ntawm biliary kua tsib outflow txoj. Tsis tshua muaj bilirubin muaj me ntsis diagnostic nqi. Yuav kom txiav txim rau theem uas koj yuav tsum tau mus soj ntsuam rau bilirubin. Cai yog txog li 20 mol / liter rau ib tug neeg laus tib neeg.
