Q

Albumin (alb)

A

Albumin is a protein that is formed within the liver. This makes up approximately 60% of the total protein. Albumin transports important blood constituents such as drugs, hormones, and enzymes.

Q

Chloride (Cl) basic chemistry test

A

Performed as part of a multiphase testing for what is usually called “electrolytes”. By itself it does not provide much information, however, with interpretation of the other electrolytes, chloride can give an indication of acid-base balance and hydration status.

Q

Creatinine Kinase M.B. (ckmb) basic chemistry test

A

The MB on the end of CK relates directly to the isoenzyme of the cardiac muscle. This test is an extended cardiac enzyme giving a more definitive diagnosis of myocardial infarction.

Q

Glycosylated Hemoglobin (Hemoglobin A1C, HbA1c) basic chemistry test

A

This test is a reflection of the blood glucose on the red blood cells during the past 3 months.

18
Q

HDL Cholesterol (HDL Chol) basic chemistry test

A

Good cholesterol, often done in conjunction with total cholesterol.

19
Q

Iron / Total Binding Capacity (Fe / TIBC) basic chemistry test

A

Useful in diagnosing anemia, some infections, and cirrhosis of the liver.

20
Q

Lactate-dehydrogenase (LD / LDH) basic chemistry test

A

A component of cardiac enzymes. LDH is an enzyme released into the circulation after tissue damage to heart, liver, kidney, brain, or skeletal muscle.

21
Q

Drug Levels basic chemistry test

A

Test for drug levels, based on the type of drug and how long the patient has been taking the drug. Most often the test is done 6hrs after the last dose of medication. These are not to evaluate how the patient’s body is utilizing the medication.

22
Q

Phosphate / Phosphorus (PO / PO4) basic chemistry test

A

To evaluate the level of phosphorus in your blood and to aid in the diagnosis of conditions known to cause abnormally high or low levels.

23
Q

Potassium (K) basic chemistry test

A

To determine whether your potassium concentration is within normal limits and to help evaluate an electrolyte imbalance; to monitor chronic or acute hyperkalemia or hypokalemia.

24
Q

Protein Total (Prot) basic chemistry test

A

Ordered to determine your nutritional status or to screen for certain liver and kidney disorders as well as other diseases.

25
Q

Protein Electrophoresis (P Elect) basic chemistry test

A

To help diagnose and monitor multiple myeloma and a variety of other conditions that affect protein absorption, production, and loss as seen in severe organ disease and altered nutritional states.

26
Q

Sodium (Na) basic chemistry test

A

To determine whether your sodium concentration is within normal limits and to help evaluate electrolyte balance and kidney function.

27
Q

Troponin (Trop / Trop level) basic chemistry test

A

Used to diagnose a myocardial infarct (both before and after the event).

28
Q

Thyroid Stimulating Hormone (TSH) basic chemistry test

A

To screen for and help diagnose thyroid disorders; to monitor treatment of hypothyroidism and hyperthyroidism.

29
Q

Uric Acid basic chemistry test

A

To detect high levels of uric acid, which could be a sign of gout, or to monitor uric acid levels when undergoing chemotherapy or radiation treatment.

30
Q

Cholesterol (Chol) basic chemistry test

A

It’s important that the food cholesterol, or high-density lipoproteins (HDL), be measured in relationship to total cholesterol.
