Vawiin hian naupai thla thum hnihnaah thisen test bik kan sawi dawn a ni. Hei hi ‘Quad Screen’ emaw ‘Quad Marker Screen’ emaw an ti a.
A awlsam zawngin Quad Screen hi eng nge ni?
Hei hi thisen test awlsam tak a ni. I naupai atanga kar 15 leh kar 20 inkarah tih thin a ni. He test hian i doctor hnenah i naute piang lai chu Down syndrome ang chi genetic condition a neih theihna tur a awm em tih hriatna engemaw zat a pe thei a ni.
Engvangin nge hei hi "Quad" an tih?
"Quad" tih hi Mizo tawngin pali tihna a ni. Chuvangin he test hi i thisena thil chiang pali level a teh avangin hetiang hi an ti a ni. Chu thil palite chu:
- AFP (Alpha-fetoprotein) a ni a, a chhuahna tur hmun leh a hmanna tur a awm lo.
- HCG (Mihring chorionic gonadotropin) tih hi a awm a.
- Estriol (estrogen chi khat) .
- Inhibin-A tih a ni
Heng test te hian eng nge an zawn?
Quad Screen hian naute chu genetic condition engemaw zat avanga hlauhawm a nih leh nih loh a zirchiang ber a ni. Condition lian ber ber thenkhat chu:
- Trisomy 21: Down syndrome tia kan hriat vek natna.
- Trisomy 18: Edwards syndrome tih hming pu natna a ni.
- Neural tube defects (NTDs): Nausen thluak leh ruhro (spinal cord) hmasawnna lama harsatna a awm.
Mahse hetah hian i hriatthiam ngei ngei tur thil pakhat a awm . Hei hi ‘screening’ test mai a ni. Chu chu risk assessment chauh a ni tihna a ni. He test hian naute hian natna engemaw tak a nei ngei ang tih 100% in a sawi lo. Risk engemaw zat a awm tih a tilang mai a, chuvangin test belh a ngai mai thei.
He test hi lak ngei ngei tur a ni em?
No. Hei hi test ngei ngei tur a ni lo. I duh phawt chuan i ti thei ang. Amaherawhchu, naupai enkawltu doctor-te chuan he test hi tih a \ha tih an rawt tlangpui. A chhan chu naute hriselna chungchangah hian a hmain ngaihtuahna engemaw zat a pe thei che a ni.
Hei hi kalphung awlsam tak a ni. I tih tur chu i kut atanga thisen sample te tak te lak mai a ni. Minute 5-10 vel a ni. Nangmah emaw, i naute emaw a tichhe lovang. Chuvangin ngaihtuah buai a ngai lo.
Thisenah thil 4 zawn tur leh a awmzia
Tunah chuan inthlak danglamna level palite hian eng nge a awmzia tih hi han en ila. Hei hi a buaithlak deuh mai thei, mahse awlsam takin ka sawifiah ang.
| Thisen a thil tehna chu | A level atanga chhiar tur chu |
|---|---|
| Alpha-fetoprotein (AFP) hmanga siam a ni. | Naute thin (liver) atanga siam a ni. AFP level a sang hle a nih chuan , neural tube defects ang chi conditions a awm theihna a tilang thei. Mahse, a chang chuan AFP level hi kar tlemte i naupai emaw, twins i pai a nih chuan a sang thei hle. AFP level a hniam chuan Down syndrome a awm theihna a tilang thei. |
| Estriol (uE) a ni. | He hormone hi naute leh nausen (placenta) te hian an siam chhuak vek a ni. Level hniam chuan Down syndrome vei theihna a sang tih a tilang thei. |
| Mihring chorionic gonadotropin (hCG) hman a ni. | He hormone hi nausen (placenta) atanga siam a ni. hCG level pangngai aia sang chuan Down syndrome vei theihna a tipung thei a ni. |
| Inhibin-A tih a ni | He protein hi i ovaries leh placenta atanga siam a ni. A level chu beisei aia sang a nih chuan Down syndrome nei naute neih theihna a tipung thei a ni. |
Ka sawi nawn leh a, hengte hi risk factors chauh a ni. Heng level pakhat hi a danglam vang mai mai chuan naute hian harsatna a nei dawn tihna a ni lo. I doctor chuan heng result te hi thil dang, i kum ang chi nen a khaikhin ang a, a hlauhawmna a teh ang.
Engtin nge result i hmuh theih?

A result chu ‘Normal’ a nih chuan engtin nge ni ang?
A result chu ‘Normal’ emaw ‘Negative’ emaw a nih chuan i naute hian a chunga kan sawi tak genetic condition a neih theihna chance a hniam tihna a ni. Chutiang hunah chuan doctor chuan genetic test dang neih belh a rawt lo fo ang. Amaherawhchu, ‘low risk’ a nih pawhin 100% in harsatna a awm lo tihna erawh a ni lo. Mahse a risk a hniam hle tihna a ni.
A result chu ‘Abnormal’ a nih chuan engtin nge ni ang?
Lungngai suh. ‘Abnormal’ emaw ‘Positive’ result a awm chuan naute hian natna a nei tihna a ni lo. Risk a sang tihna a ni a , test dang neih belh a ngai tihna chauh a ni .
Hetih lai hian i doctor chuan a bia ang che a, a hnua i tih tur chu a hrilhfiah ang che. Test dang engemaw zat pawh an rawt thei bawk.
- Detailed Ultrasound Scan: Hei hian naute taksa insiam dan chiang takin a hmu thei a ni.
- Amniocentesis: Hei hian naute chhehvela amniotic fluid sample tlemte lak a, naute cell-te enfiah a, genetic condition hriat a huam a ni. He test hian risk tlem a nei a, chuvangin thutlukna siam hmain doctor nen sawiho hmasak a pawimawh.
NIPT leh Quad Screen hi eng nge an danglamna?
NIPT (Noninvasive Prenatal Testing) tih test tih pawh i hre tawh mai thei. Risk enfiahna screening test a ni bawk.
- NIPT test hi naupai atanga kar 10 hnuah pawh tih theih a ni. I thisena nausen DNA awm chu a zirchiang a, risk a teh thin.
- Quad Screen hi second trimester ah tih thin a ni . Naute DNA a en lo va, i thisena hormone leh protein awm zat a en zawk a ni.
Heng test pahnihte hi risk tehna ‘screening’ test a ni a, ‘diagnostic’ test a ni lo. I doctor nen inbia la, eng test nge i tan a tha ber tih rel rawh.

Take-Home Thuchah a ni
- Quad Screen hi naupai thla hnihna chhunga thisen test ngei ngei tur a ni lo.
- Hei hian naute chu Down syndrome ang chi genetic condition nei thei tura hlauhawm a nih leh nih loh a teh a ni.
- Hei hi risk tehna ‘screening’ test a ni a, natna chiang taka hriat theihna ‘diagnostic’ test a ni lo.
- Result ‘Abnormal’ a nih chuan hlauthawng suh, test belh a ngai tihna chauh a ni.
- Eng test pawh i tih hmain leh result i hmuh hnuah i doctor nen i ngaihtuahna leh rinhlelhna zawng zawng sawipui hmasa phawt ang che.
