1. Gwajin D-dimer na plasma gwaji ne don fahimtar aikin fibrinolytic na biyu.

Ka'idar dubawa: An shafa wa kwayar halittar monoclonal ta anti-DD a kan ƙwayoyin latex. Idan akwai D-dimer a cikin plasma mai karɓa, amsawar antigen-antibody zai faru, kuma ƙwayoyin latex za su taru. Duk da haka, wannan gwajin na iya zama tabbatacce ga duk wani zubar jini da ke faruwa tare da samuwar gudan jini, don haka yana da ƙarancin takamaiman bayani da kuma babban ji.

2. Akwai hanyoyi guda biyu na D-dimer a cikin jiki

(1) Yanayin da za a iya haɗakar da jini da kuma yanayin fibrinolysis na sakandare;

(2) toshewar jijiyoyin jini;

D-dimer galibi yana nuna aikin fibrinolytic. Ana ganin ƙaruwa ko tabbatacce a cikin hyperfibrinolysis na biyu, kamar yanayin coagulation mai yawa, coagulation mai yaɗuwa a cikin jijiyoyin jini, cututtukan koda, ƙin dashen gabobi, maganin thrombolytic, da sauransu.

3. Muddin akwai aikin thrombosis da fibrinolytic a cikin jijiyoyin jini na jiki, D-dimer zai ƙaru.

Misali: toshewar zuciya, toshewar kwakwalwa, toshewar huhu, toshewar jijiyoyin jini, tiyata, ƙari, toshewar jijiyoyin jini, kamuwa da cuta da kuma toshewar kyallen takarda na iya haifar da karuwar D-dimer. Musamman ga tsofaffi da marasa lafiya da ke asibiti, saboda bacteremia da sauran cututtuka, yana da sauƙi a haifar da toshewar jini mara kyau kuma yana haifar da karuwar D-dimer.

4. Takamaiman da D-dimer ya nuna ba ya nufin aikin da ke cikin wani takamaiman cuta, amma ga halaye na yau da kullun na wannan babban rukuni na cututtuka tare da coagulation da fibrinolysis.

A ka'ida, samuwar fibrin mai haɗin gwiwa shine thrombosis. Duk da haka, akwai cututtuka da yawa na asibiti waɗanda zasu iya kunna tsarin coagulation yayin faruwa da haɓaka cutar. Lokacin da aka samar da fibrin mai haɗin gwiwa, tsarin fibrinolytic zai kunna kuma za a samar da fibrin mai haɗin gwiwa don hana "tarinsa" mai yawa. (thrombus mai mahimmanci a asibiti), wanda ke haifar da haɓaka D-dimer sosai. Saboda haka, haɓaka D-dimer ba lallai bane ya zama thrombosis mai mahimmanci a asibiti. Ga wasu cututtuka ko mutane, yana iya zama tsarin cututtuka.
