Lec Lesson 2 Flashcards
Important in determining which blood can be used safely
Blood bank specimen
M blood banking what tube is used?
EDTA or red tube
Age and weight for blood donors
17 to 66 and 110 lbs.
Unit of blood is separated into:
RBC’S, plasma, and platelets
Blood of patient is salvaged
Cell salvaging
Too many bacteria in circulation
Septic shock
Checks blood for pathogen
Blood culture
Presence of microorganism and toxins causes
Septicemia
Existence of bacteria un blood
Bacteremia
For optimum results in blood culture, the collection should hay now many bottles and drawn within
2-4 blood culture sets in special bottle, 30- 60 minutes apart
Prevents contamination by microbial flora in the skin
Skin antisepsis
What collection takes first priority In order of draw
Blood culture
3 ways to inoculate the medium
1.) directly into the bottle
2.) in as syringe
3.) through intermediate collection tube
Why are intermediate collection tube not recommended
Because SPS increases its concentration
Assesses the blood clotting functions
Coagulation tests
Test dowe if patient is suffering from diabetes
2-hour postprandrial glucose
Test for people who suffer from carbohydrate metabolism problems
Glucose tolerance test
Measure the ability to tu body to process lactose
Lactose tolerance test
Performed to exclude the possibility of paternity
Parentage testing
DNA paternity testing uses
genetic fingerprinting or DNA profiling
Measures drug levels at designated intervals
Therapeutic drug monitoring
This is performed by drawing a large volume of blood about 500ml as treatment for polycythemia and hemachromatosis
Therapeutic phlebotomy
Is the overproduction of red blood cells that is harmful to the patient
Polycythemia
Excess iron deposits in the tissues which could be due to problems with iron metabolism
Hemachromatosis
Collection of blood, hair, urine, and other substances for the purpose of determining the presence of toxin
Toxicology specimens
Ordered by law enforcements agencies
Forensic specimens
Tracking the specimen from the time of collection until the time that the results are released using a special protocol
Chain of custody
This test is usually ordered for purposes related to the treatment, but could also be for industrial or work related purposes
Blood alcohol specimens
This order is for individuals involved in traffic related incidents
Blood alcohol concentration
Companies, healthcare organizations, and sports associations subject their employees to these
Drug screening
This testing checks for aluminum, arsenic, copper, lead, iron, and zinc
Trace elements
Analytical tests done outside the centralized laboratory near the site where the patient receives treatment
Point-of-care testing
Other names for POCT
Alternate site testing, bedside testing, near-patient testing, remote testing, satellite testing, rapid diagnostic
This should be followed during the conduct of POCT
Quality control
Can detect specimen related problems
Electronic quality control
Non-instrumented test ordered by the physician to evaluate the capillaries for platelets plug information
Bleeding time
POCT that is quite expensive due to reduced time
Arterial blood gases and electrolytes
Measures the level of oxygen, co2, and acid base in the blood which gives status function of the liver and kidney
Arterial blood gas
Normal range of arterial pH
7.35 to 7.45
Indicator of how well air is exchanged between the blood and lungs
PCO2
Aid in moving nutrients in the body to remove waste in cells
Electrolytes
High sodium
Hypernatremia
Low sodium
Hyponatremia
High potassium
Hyperkalemia
Low potassium
Hypokalemia
Small portable testing device used to measure analytes as sodium, potassium, chloride, and bicarbonate
Multiple-test panel monitoring
Checks the presence of b-subunit of human chorionic gonadtropin
Pregnancy testing
Gauge the effectiveness of the thrombolytic therapy for people who suffered from heart attacks
Cardiac troponin and troponin I
Measures the alanine transferase
Lipid testing
Differentiates chronic obstructive pulmonary disease and congestive heart failure
B-type natriuretic peptide
Detects and evaluates infection, tissue injury, and other inflammations
C-reactive proteins
Monitors glucose level
Glucose
Diagnostic for diabetes
Glycosylated hemoglobin
Measures volume of blood cells
Hematocrit
Checks hemoglobin levels
Hemoglobin
Evaluates the severity of the lactic acid disorder and stress response
Lactate
Detects GTI bleeding
Occult blood or Guaiac
Detects human chorionic gonadtropin
Pregnancy test
Checks allergens
Skin test
Detects presence of group A streptococci
Strep testing
Analysis of urine
Urinalysis
