Nurses and tech friends, this is the third batch of the most important Nursing laboratory test that every nurse enthusiast should know by heart. It is not only the doctors and medical technologists that must know these tests but the nurses as well. For tech lovers, it also does not hurt to know something about this.
- Guthrie test – test for phenylalanine levels to diagnose PKU
- Nitrazine test – test for acidity / alkalinity; red for acid and blue for alkaline
- Fern test – microscopic exam to determine rupture of membrane (ROM), (+) if there’s NaCl fern-like crystal seen
- Post-coital test – done within 1-2 days of presumed ovulation, a test for fertility; determine the number and motility of sperm
- Beutler test – like Guthrie test but this is to screen for galactosemia
- Scotch tape test – done before bowel movement early in the morning to detect pinworms
- Patch test – introduce an allergen into the skin to detect allergies
(refer to the picture)
- Tensilon test – a test for myasthenia gravis to determine whether it is myasthenic / cholinergic crisis by administering Edrophonium (Tensilon); if symptoms intensify, it is cholinergic
- Voice test – examiner stand 1-2 feet away and let the patient block 1 ear; the examiner whispers a statement and asks the patient to repeat it. Each ear is tested separately
- Serum trough and peak level – to know the effectiveness of gentamicin by getting a sample 30 minutes before and 30 minutes after the 3rd dose is given
- Fluorescent treponemal antibody absorption test – specific for syphilis
- (RAIU) radio active iodine uptake test – if increased then hyperthyroidism; if decreased then hypothyroidism
- ANA (anti-nucleic antibody test), then Coomb’s test then Complement test – most definitive tests for SLE
- Glucose tolerance test – NPO (nothing per orem or nothing taken per mouth) during pre-procedure, drink high CHO (carbohydrate) substance then take the patient’s glucose level an hour after. An increase means impaired glucose tolerance if negative DM (diabetes mellitus)
- Non-stress test – an evaluation of fetal heart rate response to natural contractile activity
- Ishihara color test - numerous plates with colored dots and pattern; if unable to read pattern then suggestive of color blindness (Blue, Green, Red for adults while Red, Orange, Yellow for elderly)
- Bjernum tangent plate – to test central vision, if lost central vision then suggestive of macular degeneration
- AIMS(Abnormal Involuntary Movement Scale) – used to assess tardive dyskinesia
- Tine (prick) test – usually the first test done to detect TB, done before PPD, there’s a disk with tuberculin antigen used to puncture the skin
- Tissue culture test – to test for the virus present
- Sensitivity test – tests for bacteria present for prescription of antibiotics
- Trendelenburg test – raise legs to inspect for varicosities
- Anti-nuclear antibody test – test also used in rheumatoid arthritis

- Coomb’s test – test for Rh compatibility like between mother and newborn to rule out erythroblastosis fetalis
- Iliopsoas muscle test – done to test for appendicitis wherein patient’s legs are raised off the bed and a force is applied to the upper thigh while the patient opposes the force
- Obturator muscle test – test for ruptured appendicitis, done with patient in supine position and his right leg is flexed at the hip and knees must be kept at 90° angle; afterwards internal rotate the right ankle
- Antistreptolysin-O-titer (ASO titer) – used to diagnosed rheumatic fever

- Glucose tolerance test – test for blood glucose level taken at regular intervals after giving standard dose of glucose
- Kleihauer Betke test – detect whether blood is fetal or maternal in origin
- Radioimmunoassay test (RIA) – Human Chorionic Gonadotrophin (Hcg) test for pregnancy; uses serum
- Enzyme-linked Immunosorbent Assay test (ELISA) – Hcg test for pregnancy, uses urine or serum
- Hepatojugular reflux – done to test for right sided heart failure wherein pressure is applied on ones abdomen for 30-60 seconds. A sustained increase in central venous pressure (CVP) or jugular distention is a positive result
