Laboratory Guide Sheet

The following explanations are intended as a brief guide to help you understand your recent medical tests.  If you have any questions, feel free to make an appointment to learn more.


CBC-WBC: the white blood cell count indicates the presence or absence of certain typed of infections.  WBC may be high in stress or if taking steroids. Low WBC may be from a viral illness.

HEMATOCRIT (HCT)/ HEMOGLOBIN: This indicates the presence or absence of anemia. Anemia as countless reasons that can be investigated.

MEAN CORPUSCULAR VOLUME (MCV):  the size of the red blood cell. If it’s too high or low, it can be from deficiencies of B12, iron, folate; lead toxicity; or thyroid disease.

PLATELETS: These are clotting cells to stop bleeding.

ESR (sed rate)/ CRP: This is a general indicator of inflammation, and is followed.

CRP-H.S.: This test reflects risk of having a heart attack or stroke, because inflammation implies that someone’s plaque in the arteries can rupture and cause a clot.

GLUCOSE*: This is a measure of blood sugar, hypoglycemia, and diabetes.**

BUN*/ CREATININE*: This measures the ability of the kidney to get rid of bodily poison.**

SODIUM*, POTASSIUM*, MAGNESIUM, CALCIUM: These are electrolytes in the body that have to do with muscle function and heart irritability, and can be affected with dehydration.**  They also can relate to palpitations and muscle aches and spasms.

PROTEIN/ ALBUMIN: These are blood components that are general reflections of the state of nutrition of the body and the function of the liver.**

BILIRUBIN: This is the so-called yellow pigment in the blood that is a reflection of the liver metabolism.**

ALKALINE PHOSPHATASE, LDH, GGTP, AST, ALT: These are all liver enzymes that can be elevated in a number of states related to diet, infections, medication effect, and alcohol ingestion.**

ALKALINE PHOSPHATASE: When it is low, it can imply many other problems. Like zince deficiency and celiac disease.

URIC ACID: This is a chemical normally excreted by the kidney that can settle in the joints to cause gout or can cause kidney stones.**

IRON: This is a measurement used to evaluate anemia and certain other states.

TRIGLYCERIDE: This is a fat in the blood that is primarily related to intake of carbohydrates.

CHOLESTEROL: The total cholesterol is the sum of the LDL (bad), HDL (good) and VLDL (very low density lipoproteins.) Theses can indicate your relative risk for having heart and stroke problems.

HOMOCYSTEINE: An elevated number can correlated with risk for heart disease. It usually reflects a deficiency in B12, Folate and B6.

LDL- GGE: This reflects size of LDL particle; it’s another indicator of risk of heart disease.

THYROID, TSH, T4, FREE T4: This measures the hormone in the blood that controls the body’s metabolic rate. Abnormal values are seen in low and high thyroid. Signs of low thyroid include dry skin, irregular menses, and fatigue.

PSA: This is the prostatic specific antigen that is used to evaluate the possibility of prostate cancer.  It can also be seen elevated in certain prostate inflammations.

GLYCOHEMOGLOBIN OR A1C:  This is a test that gives one an average blood sugar level over the last several months, important to monitor people with diabetes.



URINALYSIS: This is a common test used to detect dehydration, blood and sugar in the urine.  It can also detect things such as protein and fat breakdown products (ketones) and can indicate infections in the urinary system).

URINE FOR N-TELEOPEPTIDES: This correlates rate of bone loss, to monitor a patient with osteoporosis.


STOOL EXAMINATION FOR BLOOD:  This is an indication of whether there might be irritation somewhere in the intestinal tract causing blood (for example: hemorrhoids, polyps, cancer, ulcers, etc.)

CDSA & PARASITOLOGY: Alternative Lab to test function of digestive and   absorption and bacteria and parasites.


CHEST X-RAY: This is a study to detect enlargement of the heart pneumonia, fluid, or nodules in the lung.

MAMMOGRAM: This is a test that can screen the breasts for lumps or cysts, but must always be correlated clinically.

BONE DENSITY: This is a test to determine whether one has thin bones (osteopenia) or very thin bones (osteoporosis)


ELECTROCARDIOGRAM OR “EKG”: This is a map of the electrical field of the heart, but must be interpreted in light of the whole clinical picture since it can be normal with an abnormal heart and can be abnormal with a “normal heart”.  It can indicate the presence of irregular heart rhythms, scars on the surface of the heart, or thickening of the walls of the heart.

ECHOCARDIOGRAM: This is a test that measures the chambers of the heart to see whether the heart is flabby or whether clots are present on the inside of the heart.  It can detect “stiff areas” where cholesterol may be present.

HOLTER MONITOR:  This is a 24-hour EKG test that detects whether the heart is going too fast or slow, whether there are premature beats, or whether there are silent circulatory problems in the heart.

TREADMILL EXAMINATIONS (TMST):  This is a test used to detect coronary artery disease, as with the EKG, it must be interpreted in light of the clinical status of the patient, since it can be normal with an abnormal heart and vice versa.

STRESS ECHOCARDIOGRAM: The patient rides a stationary bicycle while her heart in imaged with an ultrasound.  This test is preferred over the TMST for women to test for heart disease.


FEMALE HORMONE PANEL: This tests women’s hormone pattern over one cycle.

Adrenal Stress Index:   This tests shows adrenal function.


Vitamin B12 level:It is important for neurological health and anemia; goal is greater than 350

To replete your Vitamin B12: Take Intrini/B12 from Metagenics; 2 tabs 2 times a day fro the first week, then 1 tab 2 x a day long term.
Re-check your levels with Dr. Raisen in 90 days.
If you have poor absorption, you may need weekly B12 shots; make a follow-up appointment with Dr. Raisen to discuss this.

Folate: goal is greater than 15; it is important for heart health and female health, especially for the cervix (pap smears) and neurological system of a fetus.
To replete you folate, take Folapro from Metagenics, 1 tab 2 x a day.
Re-check your level in 90 days.

FERRITIN: It reflects your iron-stores in the body.  If it’s below 70, people may feel tired easily.  You can replete your ferritin, by eating more iron-rich foods, such as kale, collard greens and persimmons.
Also take Hemagenics from Metagenics, 1 tab  1 to 2 times a day. It may cause mild constipation. If it does, take it less frequently, and add Magnesium (Mag glycinate by Metagenics)

Vitamin D-25-OH: goal is 40 to 100.  It is important for immune system, prevention of cancers, and healthy bone density.
To replete your vitamin D, you can increase your sunlight exposure and take
D3-1000 from Metagenics, 2 tabs a day.
Re-check your levels in 90 days.

MERCURY:This is a toxin found from manufacturing, in the ocean, in the fish we eat, and in old paint.  It can easily build up in our bodies and cause damage to the nervous and immune system, just from eating sushi!  Get your whole-blood mercury level checked.
To treat elevated mercury, stop all fish, and take Sun-Chlorella, 15 small tabs (can chew or swallow) 3 x a day.
Re-check your levels in 90 days.
If they are still high, make an appointment with Dr. Raisen. You may be instructed to do a special urine test to measure mercury more accurately, and to treat with oral or IV chelating agents, to pull the mercury out of the body.

Be Aware: Public Health Advisory

Los Angeles officials have issued a public health advisory after two dead birds found in Santa Monica tested positive for West Nile Virus. The advisory has been issued to all residents of the city, including residents who live in NMS-owned properties such as LuXe@1539, Olympic Studios, LuXe@Broadway and elsewhere.

WNV is transmitted through the bite of an infected mosquito, according to the advisory. Mosquitos become infected when they feed on birds that have the disease and sometimes subsequently bite humans or animals.

The advisory lists a series of precautions that residents can take to protect themselves from WNV:

– Use insect repellant to keep off mosquitos, especially in the early morning and evening, when mosquitos carrying WNV are most apt to bite.
– Make sure the doors and windows in your apartment have tight-fitting screens, to prevent mosquitos from entering your home.
– Get rid of any sources of standing water, in which mosquitos can lay eggs.

WNV symptoms include headaches, high fever, tiredness, body aches, skin rash and swollen lymph glands.

For more information about the WNV advisory issued in Santa Monica, go here.
