Warm agglutinin (IgG) found in
Chronic anemia of SLE, CLL
Drugs methyldopa
Cold agglutinin (IgM) found in
Cold ay Malamig:)
Acute anemia of
- CLL
- Mycoplasma pneumonia
- Infectious mononucleosis
Anti Ig antibody is added to patients serum. RBCs agglutinate if RBCs are coated with Ig.
Direct Coomb’s test
Normal RBCs added to patient’s serum. Blood will agglutinate if serum has anti RBC surface Ig.

Causes of eosinophilia
Red warriors of the NCAA of Philippines
Red warrior - eosinophils Neoplasm Collagen Vascular disease Asthma Allergy Parasites
Have round densely staining nuclei that nearly fill up the entire cell
Or
Small and round with densely staining nuclei
B and T lymphocytes
Cytoplasm filled with large bluish granules. Elevated in allergic reaction only, not parasitic reactions.
Mast cells
These interact with IgE and degranulate releasing heparin, histamine and oth chemo tactic factors.
Elevated bothe parasitic and allergic : eosinophils
Kidney shaped nucleus
Monocytes
Inc during chronic inflammation (viral/fungal) and migrate to the tissue where they differentiate into macrophages.
Multi lobed nuclei with pink granules that contain hydrolytic enzymes, lysozymes and myeloperoxidase.
Neutrophils
Seronegative spondyloarthropathies
Arthritis without rheumatoid factor (no anti IgG antibody), with strong association with HLA B27 ( codes for MhC class I)
