 Cholesterol question

Hi, all--

Can someone help me, please? I've got these two sets of cholesterol results
in front of me but I have no idea what they mean. Here they are:

MALE:
Cholesterol..................157...............[<200].......mg/dL
Triglyceride.................111...............[0-200]......mg/dL
HDL Cholesterol...............28............................mg/dL
-----------HDL Reference Range (male):
-------------Favorable:.............>55
-------------Average risk:...........35-55
-------------Above average risk:....<35
LDL..........................107................[<130]......mg/dL
CHOL/HDL Ratio..............H 5.61.............[2.90-4.40]..mg/dL
-----------Chol/HDL ratio interpretation
-------------Ideal:.................<3.5
-------------Average risk:..........<4.5
-------------2x average risk:.......10.0
-------------3x average risk:.......20.0
LDL/HDL......................3.8
-----------LDL/HDL ratio interpretation:
-------------Ideal:................<1.0
-------------Average risk:.........<2.0
-------------2x average risk:.......6.0
-------------3x average risk:.......8.0

FEMALE:
Cholesterol..................153...............[<200].......mg/dL
Triglyceride..................91...............[0-200]......mg/dL
HDL Cholesterol...............37............................mg/dL
-----------HDL Reference Range (female):
-------------Favorable:.............>65
-------------Average risk:...........45-65
-------------Above average risk:....<45
LDL...........................99................[<130]......mg/dL
CHOL/HDL Ratio...............4.14.............[2.90-4.40]...mg/dL
-----------Chol/HDL ratio interpretation
-------------Ideal:.................<3.5
-------------Average risk:..........<4.5
-------------2x average risk:.......10.0
-------------3x average risk:.......20.0
LDL/HDL......................2.6
-----------LDL/HDL ratio interpretation:
-------------Ideal:................<1.0
-------------Average risk:.........<2.0
-------------2x average risk:.......6.0
-------------3x average risk:.......8.0

1. First question: What do each of these sets mean?
2. Second question: What does it mean where they say that the HDL
cholesterol is 28 for the male and 37 for the female but that the reference
range says that >55 is favorable for a male and >65 is favorable for a
female?
3. Third question: What does it mean on the set for the male where it says
CHOL/HDL Ratio H 5.61, Range 2.90-4.40?
4. Fourth: On each, what is the good cholesterol result and what is the bad one?

Thanks very much.

HDL is the "good" cholesterol; it's believed to help clear out deposits of
cholesterol from artery walls. So you want to have as high an HDL
cholesterol number as you can. 28 is pretty low for a male, and that's not
great news. Under 35 mg/dL is a risk factor for heart attack. Some people
can raise HDL by regular aerobic exercise; there aren't any medications
that just raise HDL. LDL cholesterol is the "bad" cholesterol, because
it's the kind that accumulates. At 107, it's well within the safe zone
(under 130). "Cholesterol" alone is very imprecise, but generally you want
it under 200, which is where both sets are. The "chol/HDL" ratio compares
the bad to the good: the report says that overall, the risk is between
average and twice average. The "LDL/HDL" ratio does the same, and has the
same answer.

The Female set of answers is very similar: a low Total cholesterol (good
news) with a low HDL cholesterol (bad news). The ratio puts this person in
the average to above average risk area.

The triglyceride results are well within normal ranges, and don't directly
affect heart risk at these levels.

Overall, it seems to be good news, suggesting that with a little more
regular exercise you can both bring your risk to average or below average
levels, and no change in your diet is indicated. Of course, you should
have a physician rather than someone who's just read a lot on the subject
interpret these for you, because there's no substitute for medical advice.

Now I am really confused! Cholesterol counts in the 20s and 30s!! Can
someone out there help. Several years ago,in this part of Canada at
least, Doctors stopped giving us our Cholesterol count in hundreds. e.g.
270 was Ok but 500 was not ok.
Now we are told our HTL (Good Cholesterol) is say 4.6 and our LTL (Bad
Cholesterol) is say 5.2. We are told to lay off the fats to keep the
bad stuff down and the cheapest and best way to keep the good stuff up
is exercise. Americans still use the "Hundreds" scale. Does anyone know
how to convert one into the other and can someone explain the numbers

The numbers in the less-than-10 range are mmol/L  (millimols per liter).
Multiply those by about 38 to get mg/dL (milligrams per deciliter).
Actually, I believe that the factor would vary slightly between HDL and LDL, for example, but 38 will get you in the ball park.

I don't know what is typically measured in the cholesterol tests:
the amount of protein, I imagine - in which case the conversion
factor would depend upon the average molecular weight of
these proteins and the percentage of protein contributing
to HDL and to LDL content.

To the original poster, my question refers to the fact that
LDL and HDL are not 2 types of cholesterol, but are 2 different
macromolecular aggregates containing proteins, lipids and cholesterol
(and other sterol-like molecules).  LDL (low-density lipoprotein)
tends to get trapped in the artery walls (thus trapping
oxidized cholesterol - the bad cholesterol), while HDL (high
density lipoprotein) does not get trapped.  In fact, HDL may transport
oxidized cholesterol out of the artery wall.

With respect to the multiplication factor for converting cholesterol from
mmol/l (SI units) to mg/dl, the SI Conversion Guide published by the New
England Journal of Medicine (1992) gives 38.6 as the relevant factor for
HDL and LDL as well as total cholesterol.
