La sedimentation kudi gwaji ne da ke auna sedimentation kudi, ko free faduwar jajayen kwayoyin halitta (ƙwayoyin jini) a cikin samfurin jini da aka bari a cikin bututu madaidaiciya bayan sa'a daya.

Wannan gudun ya dogara da maida hankali na furotin cikin jini. Ya bambanta musamman a cikin taron nakumburi, lokacin da matakan sunadarai masu kumburi, fibrinogen ko ma immunoglobulin sun karu. Don haka ana amfani da shi gabaɗaya azaman alamar kumburi.

Ana yin odar wannan gwajin sau da yawa a lokaci guda dahaemogram (ko adadin jini). Ana ƙara maye gurbinsa da gwaje-gwaje kamar ma'aunin CRP ko procalcitonin, wanda ke ba da damar auna kumburi daidai.

Za a iya ƙididdige ƙimar sedimentation a yanayi da yawa, musamman don:

• neman kumburi
• tantance matakin aiki na wasu cututtukan cututtuka masu kumburi irin su rheumatoid amosanin gabbai
• gano rashin daidaituwa na immunoglobulins (hypergammaglobulinemia, monoclonal gammopathy)
• duba ci gaba ko gano myeloma
• idan akwai ciwon nephrotic ko gazawar koda na kullum

Wannan gwajin yana da sauri, mara tsada amma ba takamaiman ba kuma bai kamata a sake nuna shi cikin tsari ba a gwajin jini, bisa ga shawarwarin Babban Hukumar Kula da Lafiya a Faransa.

Binciken ya dogara ne akan samfurin jini mai sauƙi, wanda zai fi dacewa a yi a cikin komai a ciki. Ya kamata a karanta adadin nakasar sa'a daya bayan tarin.

Ana bayyana sakamakon a cikin millimeters bayan sa'a daya. Adadin lalata ya bambanta ta hanyar jima'i (ya fi sauri a cikin mata fiye da maza) da kuma shekaru (mafi sauri a cikin tsofaffi fiye da na matasa). Hakanan yana ƙaruwa yayin daukar ciki da lokacin shan wasu magungunan estrogen-progestogen.

Bayan sa'a daya, gaba ɗaya, sakamakon ya kamata ya zama ƙasa da 15 ko 20 mm a cikin matasa marasa lafiya. Bayan shekaru 65, yawanci kasa da 30 ko 35 mm dangane da jima'i.

Hakanan muna iya samun ƙimayar ƙima ta al'ada, waɗanda yakamata su kasance ƙasa da:

- ga maza: VS = shekaru a cikin shekaru / 2

- ga mata: VS = shekaru (+10) / 2

Lokacin da ƙwayar cuta ta karu sosai (kusan 100 mm a kowace awa), mutum na iya shan wahala:

• kamuwa da cuta,
• m ƙari ko mahara myeloma,
• ciwon koda na kullum,

Sauran yanayi marasa kumburi kamar anemia ko hypergammaglobulinemia (misali cutar HIV ko hepatitis C) na iya ƙara ESR.

Akasin haka, ana iya ganin raguwar adadin ƙwayar cuta a cikin yanayin:

• hemolysis (lalacewar kwayoyin jajayen jinin al'ada)
• hypofibrinemia (saukar da matakan fibrinogen);
• hypogammaglobulinemia,
• polycythemia (wanda ke hana lalata)
• shan wasu magungunan hana kumburi a cikin allurai masu yawa
