Diagnostic testing phases
pretest
intratest
postest
The major focus of the pretest phase is client preparation
• The nurse must know what equipment and supplies are needed for the specific test
• Assessment of the patient to assist in determining precautions
• Providing information and answering client’s question about the procedure.
PRETEST
• It focuses on specimen collection and performing or assisting with certain diagnostic testing.
• The nurses uses of special standard precautions and sterile techniques
• Provide
emotional and
physical support while
monitoring the client as
needed (e.g., V /S, pulse
oximetry, ECG).
Correct labeling, storage, and transportation of the specimen to avoid invalid
test results.
INTRATEST
The focus of this phase is on nursing care of the client and follow up activities and
observations.
• Compare the previous and current test results
• Modify nursing
interventions as needed • Report the results to
appropriate health team members.
POSTEST
• The liquid portion of the blood (serum) is tested for serum electrolytes and enzymes
• Examples:
creatine kinase, serum glucose, hormones like thyroid hormones, substances like cholesterol and cardiac markers like troponin I
Blood Chemistry
• Blood from the radial, brachial or femoral arteries is withdrawn
• Apply pressure for 5 to 10 minutes at the puncture site because of great pressure
Arterial Blood Gas
Public Health strategy that enables early detection of several congenital health diseases via a heel-stick collection
RA 9288 or the Newborn Screening Act of 2004 Glucose-6 Phosphate Dehydrogenase Deficiency. Congenital Hypothyroidism. Congenital Adrenal Hyperplasi • Galactosemia.
Phenylketonuria.
• Maple Syrup Urine Disease. • Cystic Fibrosis.
• Biotinidase Deficiency.
Newborn Metabolic Screen
Taken to measure the blood glucose level
Capillary Blood Glucose
Provide more information about client’s health condition
Indications:
• Check for occult blood via the guaiac test • Check for dietary products and secretions • Check for the presence of ova and parasites (specimen should be warm)
• Check for bacteria and viruses
Stool Specimen
› This test uses a chemical called guaiac, which reacts with hemoglobin (the protein in red blood cells) present in stool samples.
> Guaiac smear (Hemoccult):
> Similar to the (Hemoccult) however, instead of applying the sample to a card, you might use a special applicator or a FIT kit to collect a sample in a vial.
> Fecal Immunochemical Test (FIT) or Immunochemical FOBT (IFOBT):
