Hematology Flashcards
What does high WBC and High PMN’s tell you?
Stress demargination. (Stress response - post trauma)
What does a high WBC and <5% Blasts tell you?
Leukemoid reaction - seen in burn patients or any extreme stress
(extreme demargination looks like Leukemia), Metamyelocytes => Myelocytes
What does high WBC and Bands tell you?
Left shift - they have an infection
What does high WBC and >5% Blasts tell you?
Leukemia
What does high WBC and B Cells tell you?
Bacterial infection
What diseases have high eosinophils?
"NAACP" N - Neoplasm (Lymphoma) A - Allergy/ Asthma A - Addison's disease (no cortisol -relative eosinophilia) C - Collagen Vascular disease (lupus) P - Parasites
What diseases have high Monocytes (>15%)?
"STELS" Syphilis: chancre, rash, warts TB: Hemoptysis, night sweats EBV: Teen sick for a month Listeria: Sick baby Salmonella: Food poisoning
What do high Retics (>1%) tell you?
RBC is being destroyed peripherally
What do low reticulocytes tell you?
Decreased production of bone marrow - not working right
What is Poikilocytosis?
RBC’s of different shapes
What is Anisocytosis?
RBC’s with different sizes
What is the RBC normal lifespan?
120 days
What is the RBC lifespan when there is a problem?
60-90 days (same time as the shelf life of blood bank units)
What is the Platelet lifespan?
7 days
What does “Penia” tell you?
Low Levels - (Usually due to virus or drugs)
What does “Cytosis” tell you?
High levels
What does “Cythemia” tell you?
High levels
What is the difference between Plasma and Serum?
Plasma: No RBC’s
Serum: No RBC’s or Fibrinogen
What are the Microcytic Hypochromic Anemias?
Defect in Hb synthesis (RBC small and pale) "FAST lead" F - Fe Deficiency A - Anemia of Chronic Disease S - Sideroblastic Anemia T - Alpha and Beta Thalassemia's L - Lead poisoning
What will you see with Iron Deficiency Anemia?
Increased TIBC(total iron binding capacity) associated with menses, GI bleeding, and Koilonychia (spooning of nails)
What will you see with Anemia of Chronic Disease?
Decreased TIBC (total iron binding capacity)
What will you see with Sideroblastic Anemia?
Decreased dALA synthase common with blood transfusions
What will you see with Alpha Thalassemia?
Seen in African Americans and Asian Americans (Chromosome 16- deletion)
What will you see in Beta Thalassemia?
Seen in Mediterranean’s
chromosome 122- point mutation
What will you see in Lead Poisoning?
Decreased dALA dehydrogenase
decreased Ferrochelatase
blue lines on x-ray
history of eating old paint chips
What are the Megaloblastic Anemias?
Vitamin B-12 Deficiency
folate deficiency
alcohol
What are some causes of Vitamine B12 deficiency?
Tapeworms
Veganism
Type A gastritis
Pernicious Anemia
What are some causes of Folate Deficiency?
Old food, you will see Glossitis(inflammation of tongue) with the patient
What is the effect of Alcohol on the fetus?
FAS (Fetal Alcohol Syndrome) Smooth philtrum (space between nose- mouth, normal people have dimple) short polyclonal midface hypoplasia thin superior Vermilion border
What are the Intravascular Hemolytic Anemias?
IgM G6PD deficiency
cold autoimmune
What are some causes of G6PD Deficiency?
Sulfa drugs, mothballs, fava beans, sudden drop in Hb
What are some causes of Cold Autoimmune?
Mono
Mycoplasma infection
Antibody (IgM) bind to RBC’s membrane
cold temp and causes agglutination
What are the Extravascular Hemolytic anemias?
Spherocytosis
warm autoimmune
Paroxysmal cold autoimmune
Sickle cell anemia
What is seen in Spherocytosis?
Defective Spherin or Ankyrin
Positive Osmotic Fragility test
High level of MCHC (Mean corpuscular hemoglobin concentration)
teardrops cells
What is seen in Warm Autoimmune?
Anti-Rh Ab Dapsone, PTU, antimalarials, and sulfa drugs
Antibody (IgG) binds to RBC’s membrane in warm temp
