• Neutrophils (polymorphonuclear leukocytes; PMNs)
• Band hlwb (me ntsis tsis paub qab hau neutrophils)
• T-hom lymphocytes (T hlwb)
• B-hom lymphocytes (B hlwb)
• Monocytes
• Eosinophils
• Cov Pob Tsuas

T thiab B-hom lymphocytes yog qhov sib txawv ntawm lwm tus hauv kev npaj swb li ib txwm ua. Ib qho kev kis mob lossis mob hnyav yuav ua rau WBCs nce ntxiv. Qhov no feem ntau yog qhia cov lej ntawm lub hlwb thiab qhov nce ntawm qhov feem pua ​​ntawm lub hlwb tsis tiav (feem ntau yog band zcells) hauv cov ntshav. Qhov kev hloov pauv no yog hais txog "hloov mus rau sab laug". Cov tib neeg uas muaj tus mob caj dab (splenectomy) muaj qhov nce qis me ntsis ntawm WBCs. Cov tshuaj uas yuav ua rau kom WBC ntau ntxiv suav nrog epinephrine, allopurinol, tshuaj aspirin, chloroform, heparin, quinine, corticosteroids, thiab triamterene.

Tej kev coj noj coj ua.

WBC - 4,500 txog 10,000 hlwb / mcl. (Faj seeb: hlwb / mcl = hlwb ib microliter).

Dab tsi txawv txav tshwm sim.

Cov lej qis ntawm WBCs (leukopenia) yuav qhia tau tias:

• Cov mob hlwb pob txha tsis ua haujlwm (piv txwv, vim muaj granuloma, qog, fibrosis)
• Muaj cov cytotoxic tshuaj collagen-vascular kab mob (xws li lupus erythematosus)
• Kab mob ntawm daim siab los yog tawg plab tawg

Cov lej siab ntawm WBCs (leukocytosis) yuav qhia tau tias:

• Kab mob sib kis mob (xws li mob rheumatoid mob caj dab lossis ua xua)
• Mob ntshav siab
• Kev mob siab los yog lub cev hnyav ua rau lub cev puas tsuaj (piv txwv li kub hnyiab)
