Hemoglobin e phahameng kapa e tlase: seo e se bolelang le litekanyetso tsa litšupiso

Litaba

• Hemoglobin e nang le 'mele
• Hemoglobin morong

Hemoglobin, kapa Hb, ke karolo ea lisele tse khubelu tsa mali mme mosebetsi oa eona o ka sehloohong ke ho tsamaisa oksijene ho lisele. Hb e na le sehlopha sa heme, se entsoeng ka tšepe, le liketane tsa globin, tse ka bang alpha, beta, gamma kapa delta, tse hlahisang mefuta e meholo ea hemoglobin, joalo ka:

• HbA1, e entsoeng ka liketane tse peli tsa alpha le liketane tse peli tsa beta mme e teng ka bongata bo phahameng maling;
• HbA2, e entsoeng ka liketane tse peli tsa alpha le liketane tse peli tsa delta;
• HbF, e entsoeng ka liketane tse peli tsa alpha le liketane tse peli tsa gamma mme e fumaneha ka bongata ho masea a sa tsoa tsoaloa, 'me mahloriso a bona a fokotsehile ho latela kholo.

Ntle le mefuta ena ea mantlha, ho ntse ho na le Hb Gower I, Gower II le Portland, tse teng nakong ea bophelo ba embryonic, ka ho fokotseha ha mohopolo oa bona le keketseho ea HbF ha tsoalo e ntse e atamela.

Hemoglobin e nang le 'mele

Glycated hemoglobin, eo hape e bitsoang glycosylated hemoglobin, ke teko ea tlhahlobo e ikemiselitseng ho lekola palo ea tsoekere ea bongaka maling nakong ea likhoeli tse tharo, e loketse ho hlahlojoa le ho lekola lefu la tsoekere, le ho lekola ho teba ha eona.

Boleng bo tloaelehileng ba hemoglobin e nang le glycated ke 5.7% mme lefu la tsoekere le netefatsoa ha boleng bo lekana kapa bo fetang 6.5%. Ithute haholoanyane ka hemoglobin e nang le glycated.

Hemoglobin morong

Boteng ba hemoglobin morotong bo bitsoa hemoglobinuria mme hangata bo supa ts'oaetso ea liphio, malaria kapa chefo ea lead, mohlala. Ho khetholla haemoglobin morotong ho etsoa ka tlhahlobo e bonolo ea moroto, e bitsoang EAS.

Ntle le hemoglobin, boleng ba hematocrit bo bonts'a liphetoho maling joalo ka khaello ea mali le leukemia. Bona hore na hematocrit ke eng le hore na u ka utloisisa sephetho sa eona joang.
