The normal triglyceride level is less than 150 mg/dL (1.7 mmol/L). [1] [5] Once diagnosed, other blood tests are usually required to determine whether the raised triglyceride level is caused by other underlying disorders ("secondary hypertriglyceridemia") or whether no such underlying cause exists ("primary hypertriglyceridaemia"). There is a ...
[VLDL] = [Triglycerides] / 5 The alternative calculations mentioned above may yield significantly different values for VLDL. The Friedewald method is reasonably reliable for the majority of patients, but is notably inaccurate in patients with hypertriglyceridemia (> 400 mg/dL or 4.5 mmol/L). It also underestimates LDL-C in patients with ...
Triglyceride level is an independent risk factor for cardiovascular disease and/or metabolic syndrome. [37] Food intake prior to testing may cause elevated levels, up to 20%. Normal level is defined as less than 150 mg/dL. [46] Borderline high is defined as 150 to 199 mg/dL. [46] High level is between 200 and 499 mg/dL. [46]
The osmol gap is typically calculated with the following formula (all values in mmol/L): = = ([+] + [] + []) In non-SI laboratory units: Calculated osmolality = 2 x [Na mmol/L] + [glucose mg/dL] / 18 + [BUN mg/dL] / 2.8 + [ethanol/3.7] [3] (note: the values 18 and 2.8 convert mg/dL into mmol/L; the molecular weight of ethanol is 46, but empiric data shows that it does not act as an ideal ...
where H is HDL cholesterol, L is LDL cholesterol, C is total cholesterol, T are triglycerides, and k is 0.20 if the quantities are measured in mg/dL and 0.45 if in mmol/L. There are limitations to this method, most notably that samples must be obtained after a 12 to 14 h fast and that LDL-C cannot be calculated if plasma triglyceride is >4.52 ...

LDL total cholesterol – HDL – (0.2 x fasting triglycerides). [43] However, this equation is not valid on nonfasting blood samples or if fasting triglycerides are elevated (>4.5 mmol/L or >~400 mg/dL). Recent guidelines have, therefore, advocated the use of direct methods for measurement of LDL wherever possible. [39]
