Q: Very Low Hdl

What can be done for very low HDL? I'm a 30 yr old male, and had the following cholesterol readings a year ago:

ldl: 153
hdl: 22
triglycerides: 74

I already ate fairly healthy, though at 220lb, needed to lose some weight. I've lost 20 lbs, cut out any remaining unhealthy eating habits, increased aerobic excercise to 1hr at least 5days/wk. I usually only eat meat once per week and then typically poultry or fish. I eat the recommended 5 servings of a variety of fruits and vegetables and nearly 100% of my grains are whole grains. (helps a lot to be a decent cook to eat like that Very Happy ) A year later, I had the following readings:

ldl: 131
hdl: 23
triglycerides: 122


There's perhaps another 15lb wieght to lose, but I'm pretty close to being fairly lean, I eat well, excersize, etc. I'm going to acheive my remaining weight loss, but my concern is that despite my efforts, there's been almost no improvement in the hdl numbers--that and the triglyceride numbers got worse.

I'm also not excited about using drugs to treat the cholesterol problem since that seems to be my only choice after trying diet, excersize, etc. I also don't smoke and do not drink.

I know heredity can cause these things, but I have no way of knowing or confirming that since I'm adopted and do not know my genetic parents/family. Is there anything else to try that I'm not already doing?

On another note, my doctor ordered a followup lipid panel. My cholesterol results the first two times were from a free health screening our HMO offers by visiting our employer. They used an on site meter to give a readout of the 3 lipid numbers from a small pipet blood draw, but wanted to draw blood to confirm the numbers after the most recent results. Is there anything else a more traditional lipid panel will tell you that the meters will not? I'm still waiting the results from the blood draw for the doctor's followup test.

Re: Very Low Hdl
Well, just to follow up on the earlier post, I got results back from the blood draw and had nearly normal hdl levels. Still on the low side, but not the low 20s that two different portable meters, one year apart gave. Now I get:

ldl 105
triglyceride 62
hdl 39

All I can think is "what the heck" with regards to these test results. Except for the borderline hdl number, these numbers are pretty decent. I suppose that the blood draw/lab version was called for by my doctor to see whether the portable meter was giving bad results--is that because the portable meter tests are not always accurate? Strange that I got two seperate, consistent low hdl numbers on the portable meter test. Which should I trust?

I also have done some reading on how these levels are tested, and basically it seems that whether a particle is considered HDL or LDL is dependant on a standard range of density that apparently has changed in the past. Curiously, the sum of HDL LDL seemed to remain about the same in this round of testing. Since LDL is not measured directly but is calculated from the total, triglyceride, and HDL measures, my ~20 point swing in HDL number basically accounts directly for the ~20 point drop in LDL.

I suppose a cholesterol test is just one tool to assess risk, but I am really curious if there is any data on the reliability of these tests. I realise cholesterol numbers are not 100% predictive for health outcomes, but how accurate are the tests in getting the numbers right?
