Clinical Genetics
Back to Clinical Analysis Laboratory page
- Clinical genetic testing refers to the laboratory analysis of DNA or RNA to aid in the diagnosis of disease. Genetic testing can provide definitive diagnosis as well as help predict the likelihood of developing a particular disease before symptoms even appear.
- Genetic tests are performed on a sample of blood, hair, skin, amniotic fluid (the fluid that surrounds a fetus during pregnancy), or other tissue. For example, a procedure called a buccal smear uses a small brush or cotton swab to collect a sample of cells from the inside surface of the cheek.
- Clinical geneticists must continually take account of new discoveries that alter clinical practice. They have an important role to play in public education and debates about ethical issues arising from new developments in the clinical application of genetic knowledge.

Proteins related to inflammation
Peritoneal fluid
- When you have abdominal pain and swelling, nausea, and/or fever and your healthcare practitioner suspects you have peritonitis or ascites.
- A sample of peritoneal fluid is collected by a healthcare practitioner with a syringe and needle using a procedure called paracentesis.
- To help diagnose the cause of peritonitis, an inflammation of the membrane lining the abdomen, and/or peritoneal fluid accumulation, where fluid builds up in the abdomen or around internal organs (called ascites)
Pericardial fluid
- Pericardial fluid analysis: to evaluate and classify the type of fluid between the pericardium membranes to assist with diagnosis of infection or fluid balance disorder.
- Specimen: Pericardial fluid collected in a red- or green-top (heparin) tube for glucose, a lavender-top (EDTA) tube for cell count, and sterile containers for microbiology specimens; fluid in a clear container for cytology. Ensure that there is an equal amount of fixative and fluid in the container for cytology.
- Method: Spectrophotometry for glucose; automated or manual cell count, macroscopic examination of cultured organisms, and microscopic examination of specimen for microbiology and cytology; microscopic examination of cultured microorganisms.
Pleural fluid
- In a pleural fluid analysis, the doctor will remove fluid from the pleural membrane area by inserting a needle into the chest cavity and suctioning the fluid into a syringe (thoracentesis). This also works as a common procedure to drain the excess fluid from the chest cavity. The fluid will then be tested to determine the cause.
- Pleural biopsy involves taking a sample of tissue from the pleura. This can be done by inserting a small needle from outside the chest wall into the chest cavity.
Synovial fluid
- helps diagnosing the cause of joint inflammation, pain and/or swelling
- tested when one or more of the joints are swollen, red and/or painful
- a synovial fluid sample is obtained by inserting a needle into the space between the bones at a joint
- synovial fluid collection and analysis may be performed after fasting or at random
Saliva testing
- Saliva testing is a diagnostic technique that involves laboratory analysis of saliva to identify markers of endocrine, immunologic, inflammatory, infectious, and other types of conditions.
- Saliva is a useful biological fluid for assaying steroid hormones such as cortisol, genetic material like RNA, proteins such as enzymes and antibodies, and a variety of other substances, including natural metabolites, including saliva nitrite.
- Saliva testing is used to screen for or diagnose numerous conditions and disease states, as well as for drug testing.
- Salivary testing has even been used by the U.S. government to assess circadian rhythm shifts in astronauts before flight and to evaluate hormonal profiles of soldiers undergoing military survival training.
Amniotic fluid
- To detect and diagnose certain birth defects, genetic diseases, and chromosomal abnormalities in a fetus, especially if prenatal screening tests are abnormal.
- A sample (about 1 ounce) of amniotic fluid is obtained using a procedure called amniocentesis that involves inserting a thin needle through the belly and uterus into the amniotic sac.
Cerebrospinal fluid
- CSF is formed by a combined process of plasma ultrafiltration and active secretion.
- Mechanical and osmotic barriers exist between plasma and CSF and between CSF and brain.
- Lumbar puncture is the preferred technique for CSF sampling.
- Normal CSF should be clear, colorless, and free of clotted material.
- CSF can be examined for presence of microbes using stains.
- Additionally, the chemical composition of CSF can be examined; tests of interest include glucose, protein, lactate, enzymes, glutamine, specific amino acids, biogenic amines, and various drugs.
Urine samples
Type of urine sample How it is used
First morning sample Provides a concentrated sample of urine that contains the overnight
accumulation of metabolites. Useful for detection of proteins or
unusual analytes.
Random Convenient sample that can be collected at any time.
Most often used for routine screening tests.
Timed Typically 2 to 6 hours of urine output is collected to give a
representative sample; duration of collection depends on the
analytes.
24-hour Entire urine output for a 24-hour period is collected. Like a timed
urine, but used for metabolites whose excretion rates may vary with
time of day and full 24-hour collection is needed to be representative.

Blood collection tubes
TUBE ADDITIVE STOPPER COLOR SAMPLE COMMENT
None Red Serum Clotting requires at least 30 minutes at room temperature Silica clot activator Red/black Serum Silica speeds the clotting
process compared to no
activator
Thrombin Gray/yellow Serum Speeds clotting process
significantly to produce serum in
several minutes — used mostly
for urgent (STAT) testing Lithium Heparin Green Plasma Preferred plasma sample for
most chemistry tests — not
suitable when testing for lithium Sodium Heparin Green Plasma Used when testing for lithium—
not suitable when testing for
sodium
EDTA Lavender Plasma Occasionally used for some
chemistry tests and typically
used for Hematology
Potassium EDTA
in special plastic tube Tan or brown Plasma For blood lead testing;
tubes are certified to have very low levels of contamination by lead
Sodium fluoride/
potassium oxalate Gray Plasma For glucose testing — sodium
fluoride inhibits metabolism of
glucose by white blood cells
