Low(ish) triglycerides (barely above 50)?

My triglycerides count is 51 - it would seem the minimum count is 50. So what - if anything - does this mean?

Here is the scale as recommended from the American Heart Association: Level mg/dL Level mmol/L Interpretation <150 <1.69 Normal range, low risk 150-199 1.70-2.25 Borderline high 200-499 2.25-5.63 High >500 >5.65 Very high, high risk
