Hematology
A 10-14um Granulocytic cell with multi-lobed highly condensed nucleus is a first line of defense against bacterial infections.
What is a segmented neutrophil?
The instrument that measures the transmitted light of a solution and allows the absorbance of the solution to be read on a meter using Beer's law.
What is the spectrophotometer?
The test used to measure a patient hemostasis status in the extrinsic pathway when patient is taking Coumadin or Warfarin drug.
What is a Protime test?
The primary test to determine a patients ABO group antigens.
What is a Blood Type test?
This dipstick test measures the concentration of acetoacetic acid in urine with elevated amounts indicating possible DKA, fasting, pregnancy, or other carbohydrate metabolism abnormalities.
What is Ketones test?
There is a B-type and T-type of this monocytic cell with the primary function of fighting viral infections.
What is a lymphocyte?
These 3 electrolytes are used in calculating a patients Anion gap.
What are chloride (Cl), sodium(Na), and bicarbonate (CO2)?
The anticoagulant inside a Blue top test tube.
What is Sodium Citrate?
The primary naturally occurring antiglobulin type in ABO group that react best at room temperature or below.
What is the IgM antiglobulin?
Under microscopic examination, these cells display "Brownian" motion and are counted semi-quantitatively under high power.
What are bacteria cells?
This granulocytic cell is usually present in high amounts in patients with asthma or parasitic infections.
What is an Eosinophil?
The measuring method for immunoassay tests that uses chemical labels that undergo a chemical reaction and form an unstable derivative releasing energy in the form of visible light that relates directly (sandwich) or indirectly (competitive) to the concentration of reactants.
What is chemiluminescence?
These are the result of plasmin breakdown of cross-linked fibrin and testing can be used to diagnose DVT or PE in a patient.
What are D-dimers?
Immune antiglobulin type that develops in response to exposure to ABO-incompatible RBCs and can cross the placental barrier.
The IgG antibody.
Concentration of this chemical increases with longer incubation time of urine within the bladder and indicates the presence of gram-negative bacteria.
What is the dipstick Nitrite test?
Measured in femtoliters (fl), this graph type provides information for RBC, WBC, and platelet frequency distribution based on cell size.
What is a cell histogram?
This element is falsely increased in hemolyzed samples due to 20 times more of it in RBCs.
What is potassium (K)?
This is tested after diagnosis of an MI to monitor how much unfractionated heparin to administer to the patient.
What is the Anti-Xa test?
The only diagnostic test in the Immunohematology lab that detects whether a patient immune system is attacking RBCs in vivo.
What is a Direct Coombs or Direct Antiglobulin Test (DAT)?
These cells line the proximal and distal convoluted tubules and collecting ducts within the nephron and increased amounts of this cell can indicate tubular necrosis, transplant rejection, viral infections of the kidney or drug toxicity.
What are renal tubular cells (RTE)?
The automated analysis of cells passing in a fluid suspension through a laser light source by labeling the cells with monoclonal antibodies specific for a variety of cell membrane protein receptors.
What is flow cytometry?
Laboratory diagnosis of pancreatitis is primarily dependent on highly elevated amounts of these 2 analytes.
What are Triglycerides and Lipase?
This test is used to monitor a patient on heparin using the intrinsic pathway of hemostasis.
What is the Activated Partial Thromboplastin (APTT) test?
The blood group antigen that is second only to the D antigen in immunogenicity and is negative in more than 90% of the population.
What is the Kell blood group system.
These abnormal looking cells, that resemble yeast or Mickey Mouse ears under microscopic exam, can differentiate between glomerular and non-glomerular hematuria and are a sign of serious renal pathology.
What are dysmorphic RBCs?
