Q

STAT

A
  • Short turn around time
  • Performed immediately and by itself
  • Done in an hour or less
  • Run control and standard
  • 20-50% more expensive
  • TAT is shortened
  • Request is needed

The sample cannot be received without the requisition form.

Q

Routine

A
  • Done with the batch
  • Wait for TAT stated by the laboratory
  • Samples need to reach a specific number before being tested by batch

Samples need to reach a specific number before being tested by batch

6
Q

Today

A
  • Performed ASAP, given priority
  • Based on “running time”
7
Q

Reference Values (RR, ref values)

Factors that should be consider:

A
  • Pulled value, usually 95% of the population
  • Vary in diferent hospitals, but not that far
  • Not fixed for all

Better term than “normal value”

  • Age
  • Sex (male patients have higher RBC and hematocrit counts than female patients)
  • Pregnancy
  • Diurnal variation
  • Race
  • Blood type
8
Q

Critical Values

A
  • Needs** immediate attention**
  • “panic values”
  • Should call physician
  • Patient is at risk

Example
1. Potassium Levels are STAT
* low levels of K = dificulty of heart to pumpblood

9
Q

Significant Values

A
  • Clinical design should be made if higher or lower than the reference value.
  • Usually when 2x to 3x higher
10
Q

BASIC LABORATORY EQUIPMENT

A
  1. light microscope
  2. ph meters
  3. colorimeters and photometer
  4. mixers
  5. water bath
  6. ovens
  7. centrifuge
  8. balance
  9. de-ionizers
  10. safety cabinets
  11. cold incubators
  12. glassware and plasticware
  13. refrigerators
11
Q
  • Correct specimen for requested test with necessary information so that right test is carried out and result is delivered to the requesting clinician with the minimum of delay.
  • Patient identification must be correct.
  • The quality of laboratory results depends on thequality of the sample (direct relationship).
A

SAMPLING

Proper patient identification:
* Allow the ambulatory-conscious patient to verbally state their name

  • If the patient cannot (baby, coma, etc.),communicate with the guardian/provider.
11
Q

SPECIMEN TYPES

A
  1. Venous blood serum or plasma
  2. Arterial blood
  3. Capillary blood
    * Skin puncture
  4. Urine
    * Urinalysis
  5. Feces
    * Fecalysis
  6. CSF
    * Cerebrospinal fluid
    * Done by the physician through a spinal test
  7. Sputum
  8. Tissue and cells
  9. Aspirates (pleural, ascites, joint fluid, intestinal(duodenal), pancreatic fluids
  10. Calculi
    * Kidney stones
12
Q
  • Labeled as “dangerous specimen”, yellow sticker
  • Similar label should be attached to the request form
  • Stored in yellow plastic

Examples?

A

DANGEROUS SPECIMENS

  1. HBV Positive
  2. HIV Positive
  3. TB Positive
12
Q

A ____ may be added to prevent ____, or ____ ____ may be added to ____ ____ in urine samples.

Examples?

A

A Preservative may be added to prevent bacterial growth, or acid may be added to stabilize metabolites in urine samples.

  • Cold Temperature will also slow down replication of bacteria
  • AREAS/SECTIONS:
    1. Clinical Microscopy or AUBF
    2. Microbiology - for culture

Examples:
* Boric Acid
* Acetic Acid
* Toluene
* Hydrochloric Acid
* Thymol

13
Q

Sampling Errors

A
  1. Blood Sampling Technique
    * puncture should only be less than a minute
  2. Prolonged stasis during Venipuncture
  3. QNS (Quantity Not Sufficient)
  4. Errors in timing
  5. Incorrect specimen container
    * Incorrect tube for each test
    * stopper container color
  6. Inappropriate Sampling Site
  7. Incorrect Sample Storage
    * Reference temperature is 2°-8°
14
Q

PLASMA

A
  • Anti-coagulants are needed for purification
  • It can be prepared as soon as it has been mixed thoroughly
  • Fibrinogen is present (not used up)
  • Platelets and cells (WBCs) can contaminate the liquid fraction
  • The composition of ions isrepresentative of the circulating blood
  • Considered less stable (especially during longer storage)
15
Q

SERUM

A
  • Anti-coagulants are not needed
  • 30 minutes delay for a clot formation
  • Fibrinogen is absent (used up)
  • Cleaner sample, depleted of cellsand cell remnants, but latent clottingcan lead to fibrin formation
  • Clot retraction elevates potassiumlevel relative to its plasma value
  • Considered more stable – the goldstandard for biobanking
