... Great explanation...
So... here is the calculation:
Divide your Triglycerides by 5 113/5 = 22.6

... The Friedewald Formula is normaly used to estimate LDL cholesterol. The only lipids that are directly read are TC, TG and HDL. The formal uses the following calculation:
Estimation of LDL Cholesterol = Total Cholesterol – HDL Cholesterol – VLDL Cholesterol*
* Estimation of VLDL Cholesterol = Trigs/5 (Trigs/2.2 for mmol/L) (6 replies)

... Hey bigal, your forumla is identical to the one you said was wrong. You said:
LDL = TC - HDL - (Trigs/5)
Which just happens to be the same exact forumula as:
TC = LDL + HDL + (Trigs/5). (6 replies)

... No the formula is wrong the correct one is
Total cholesterol minus HDL minus the (Triglycerides divided by 5)
So here is an example Chol.=174 Trig= 296 HDL= 54 LDL=60.8
174 - 54=120
296. divided by 5=59.2
120
-59.2
60.8 (6 replies)

... If you mean that your mother had two different blood tests done at two different labs and they came up with two different TC numbers, this is not surprising. They are likely using the same testing protocol, but these numbers are not absolutes like your height. In other words, you could have the very same lab take a sample, five minutes later take another sample. Then send... (6 replies)

... I don't think it is correct that HDL and LDL are the same, you might want to go over the numbers again. LDL is typically much higher than HDL. Those numbers don't really add up properly. Call them again to get the numbers. In the US, at least, you can ask for a copy of the report as well; hopefully, you can do that there as well so you have a hard copy.

... I understand that if you divide a certai number of your cholesterol with another number, either HDL, LDL or toal, you get a number between 1,0 and 5.0 that tells you where you should be. ... (2 replies)

... and very low triglyceride level. And don't worry about that LDL of 170 because that number isn't accurate. See, on the majority of lipid tests the lab measures total cholesterol, HDL, and triglycerides but they calculate LDL rather than measure it. ... (7 replies)

... There SHOULD be no difference in the cholesterol measurement from lab to lab. ... (6 replies)

... Its not really conflicting because HDL is your "good" cholesterol which helps counteract the "bad" LDL cholesterol so keeping your LDL, HDL and trigs in range individually and having a good ratio is more important than the total (6 replies)

... The calculation seems correct. Also, I have a record of 15 blood tests starting in 1984, and the trigs are all over the place, from a low of 68 to highs of 214. ... (9 replies)

... What is your HDL (good cholesterol)? Your numbers are similar to my untreated numbers and I'm age 39. Do you exercise? I do and still have those type numbers, untreated. First, you might try diet and exercise modifications and then retest. Also, you can add Niacin (Vitamin B-3) as you may get an increase in HDL and a reduction in LDL/Total. Plus, you can try a regimen of... (22 replies)

... As a side note, the VLDL can be calculated in a couple of ways. One method is to divide the triglycerides by 5, and another is by subtracting LDL and HDL cholesterol from total cholesterol The 2nd calculation may not be entirely accurate if there are other cholesterol-containing lipoprotiens present. It will however give you a rough idea of what yours is. Dividing the... (2 replies)

... I was on statins for 8 months and had Ezetimibe added in for one month before I got my trigs down and had my first valid LDL, and that was 27. By that point my total was 124 but it was shortly after angioplasty so low due to that. ... (9 replies)
