Anemia Screen

An anemia screen checks your iron status to see if there is an abnormally high, abnormally low or a sufficient supply of iron. The screen includes a panel of tests for folate and vitamin B12 levels, hemoglobin, iron, total iron binding capacity (TIBC), and iron saturation percentage. Fasting is required for this test.

Blood Type (ABO/Rh)

Blood typing is used to determine an individual’s blood group, to establish whether a person is blood group A, B, AB, or O and whether he or she is Rh positive or Rh negative.

Complete Blood Count with Diff (CBC)

The complete blood count (CBC) is one of the most commonly performed tests because it is one of the most informative. CBC testing examines and reports on the status of your body’s red and white blood cells and includes several indicators for various diseases and disorders including anemia and infections.

Comprehensive Metabolic Panel

The comprehensive metabolic panel is a group of 14 tests that gives important information about the current status of your kidneys and liver, electrolyte and acid/base balance, as well as levels of blood glucose and blood proteins.

Drug Screen

Urine drug testing detects the presence of certain illegal drugs and prescription medications and is the only testing method approved for federally-mandated testing. Urine drug screening detects recent drug use in the previous 24 to 72 hours, but detection times can vary depending on the type of drug that was used.


A folate test helps diagnose anemia, neuropathy, and monitor the treatment of vitamin B12 or folate deficiency. Folate is necessary for the formation of normal red blood cells, the repair of tissues, and synthesis of DNA, the genetic material in cells.

Iron and TIBC Test

An iron and total iron-binding capacity (TIBC) test determines your blood iron level and shows if there is an abnormally high, abnormally low or a sufficient supply of iron. Iron is a vital oxygen-transporting mineral. Iron is absorbed from food and is necessary for the production of healthy red blood cells. Too little iron can cause anemia, while excess levels can cause medical problems as well. Fasting is required for this test.

Pregnancy Test Qualitative - Serum

A qualitative blood pregnancy test provides confirmation of the presence of the pregnancy hormone called human chorionic gonadotropin (hCG). HCG is a hormone produced by the placenta during pregnancy. Production of hCG increases steadily during the first trimester (8-10 weeks) of a normal pregnancy, peaking around the tenth week after the last menstrual cycle.

Prostate Screen (PSA)

PSA (prostate‐specific antigen) is a protein made by the cells of the prostate. The routine PSA test measures the amount of prostate‐specific antigen in the blood. Rising or changing levels of PSA may be a sign of a prostate problem, perhaps as serious as cancer.


A prothrombin time (PT) measures how long it takes your blood to clot. It is used to help detect and diagnose the cause of unexplained bleeding or inappropriate blood clots.

Testosterone Screen - Male Only

Testosterone is a hormone is important in men for sexual and reproductive development, and is responsible for building muscles and keeping the muscles and bones strong. Testosterone testing will detect an abnormal testosterone level in men. This test is for males only.

Thyroid Screen

The thyroid-stimulating hormone test, or TSH, is a blood test used to detect problems affecting the thyroid gland. Altered levels of TSH in the blood may occur in a person exhibiting symptoms of a thyroid disorder, including hyperthyroidism or hypothyroidism.


A urinalysis is a screening and/or diagnostic tool that can provide a wide range of information. This simple test screens for metabolic and kidney disorders by detecting substances such as protein or glucose in the urine. The test can also identify a urinary tract infection (UTI). For the best test results, plan to provide a urine sample early in the morning.

Vitamin B12

Vitamin B12 plays a role in making DNA and also helps keep nerve cells and red blood cells healthy.

Vitamin D

Vitamin D, sometimes called the sunshine vitamin, is a hormone produced in the body after exposure to sunlight or from consuming certain foods and supplements. Vitamin D helps maintain normal blood levels of calcium and phosphorous. It aids in the absorption of calcium, helping to form and maintain strong bones, and modulate neuromuscular, immune and other cellular functions.
