Lab Reports

The following is a brief description of what your labwork means.
Physicians may change what the high ends of normal are for you
based on risk factors.

GLUCOSE    - goal 70-109       yours__________  (diagnosis of diabetes is when 126 or above is seen 2 times)

When your body digests carbohydrates, it's broken down into glucose.  Glucose is the same thing as blood sugar.  The American Diabetes Association really wants to see fasting sugars under 100 instead of 110 because 15% of people with fasting sugars between 100-110 will go on to become diabetic. 

HbAlc (Glycosylated hemoglobin) -goal < 6.0%        yours_________

Imagine doing 100 blood sugar readings a day for three months. HbAlc is an average of all these readings without having to do all the pokes. The test actually measures the amount of sugar that attaches to protein in the Red Blood Cells.  Because red blood cells live about 3 months, the test shows the 3 month average.  HbAlc is analyzed as a percentage.  Here's a chart comparing % to glucose.

                                                                                                                  4%            60        in control
5%            90        in control
6%            120      in control
7%            150      in control
8%            180      out of control
9%            210      out of control
10%            240      out of control
11%            270      out of control
12%            300      out of control
13%            330      out of control

Reducing your Alc by just 1% greatly reduces your risk of diabetes complications.  For example, decreasing your Alc from 8% to 7% reduces your risk of eye, kidney, and nerve damage by 35%. 

TRIGLYCERIDES (TRIG)- goal <150          yours ________

Triglycerides are made when the body isn't using all of the fats and carbohydrates you eat.  When glucose floating around in the blood meets up with free fatty acids floating around, they combine and are called a triglyceride. 

Think of this as a "bad match" which you'll want to break up.  Alcohol causes matchmaking too (which increases triglycerides).  This lab will bounce around quickly.  Exercise and fiber lower TRIG. 

Total CHOLESTEROL (CHOL) goal <200         yours ________

You may even see the goal as <180 if there are other heart disease risk factors or strong genetic disposition.

Total CHOL= HDL + LDL + VLDL

Most vegetarians have a cholesterol <150.

LDL -Low-Density Lipoprotein Cholesterol    goal <130  (or <100 if other risk factors)  yours_______

This is the "bad" cholesterol.  Think Loser, Lowlife, Lousy and you want Less of them.  These are the globules that stick to arteries and clog them.  We can lower the losers by increasing soluble fiber.  Unfortunately, exercise doesn't decrease these but if you lose weight (via diet and exercise) they should come down.

HDL- High-Density Lipoprotein Cholesterol    goal over 50   yours_______

This is the "good" cholesterol.  Think Hero, Happy, Healthy, and you want them Higher.  HDL's act like the video game PacMan.  They try to keep arteries clean by preventing LDL from sticking.

Exercise will increase these.  The threshold is 7 (15 minute) segments of aerobic activity per week.  Every 15 minute segment above and beyond this will increase HDL by 0.4 points.

VLDL -Very low density lipoprotein is a globule more in transition and is not a factor yet.  It's usually 20-30 points of your total cholesterol.

RATIO- What percentage of your total cholesterol is made up of HDL (Hero's)?  goal <4.0       yours______

This is calculated   Total Cholesterol/HDL

example total 200, HDL 50         200/50 = 4.0

Sometimes people have such a high HDL that it skews the total to be higher pushing it over the 200 mark, to this is when ratio is important.  

HOMOCYSTEINE- goal < 11.4             yours ________

This is an amino acid (broken down protein) normally found in the blood however sometimes the levels become excessive.  High levels of homocysteine may damage the arteries or make blood more likely to clot.  Low intakes of folic acid and vitamin B12 seemed to be linked with higher levels of homocysteine.

CRP, CCRP or C-Reactive Peptide- goal < 1.0          yours________

This is a lab that shows inflammation in the arteries.  A higher level may indicate unstable plaques in the arteries which could break off and cause blockages, or collect more of the "pieces" floating around. This would cause a growth in thickness, which would decrease the amount of blood flow through arteries.  Omega-3 fatty acids are believed to decrease inflammation.
