What can affect the results of a cholesterol test?

Cholesterol test: What can affect the results of a cholesterol test? ANS: time of day, diet for 3+ weeks before, blood drawn before you got out of bed?, family history, your medical history, medications you are taking. Age, gender, lab error, liver failure, acute glomerulonephritis and nephrotic syndrome, starvation, eating way too much fat, or not enough, BCP, thyroid disease, cancer, being too fat/skinny. Ask Dr.

For what reasons do we need to fast before cholesterol test?

Lipids: For years we've fasted overnight as you note. Recent evidence suggests it isn't necessary. Practice is only changing slowly being cautious.

Why is my cholesterol only high with a expanded cholesterol test and not a regular one?

Why is my cholesterol only high with a expanded cholesterol test and not a regular one?

Should be similar: Your cholesterol level may vary slightly from day to day, and it can change significantly over time with changes in diet, activity or overall health. Also, there can be some variation in the levels depending on whether both were fasting samples (i.e., using blood not taken immediately after a meal). Otherwise, there should not be a big change in 2 fasting samples taken relatively close together.

Would it be possible that a cholesterol test tell you if you have diabetes?

Would it be possible that a cholesterol test tell you if you have diabetes?

No: But a high fasting triglyceride level often indicates developing Insulin resistance and early diabetes.

Might eating something high in sugar (such as a donut) before taking a cholesterol test affect the outcome?

Might eating something high in sugar (such as a donut) before taking a cholesterol test affect the outcome?

Yes: A donut with all the affed fat would affect a cholesterol and triglyceride test. Please try to fast for 12 hours before testing. Water is allowed for hydration.

I'm scared - total cholesterol test came back at 294?

I'm scared - total cholesterol test came back at 294?

Elevated but...?: Your total cholesterol is elevated but that's not enough information to determine if it's a risk for you. What was you LDL and HDL (if you have a high HDL, it mitigates the high TC). What are your other risks? Do you have known heart disease? Diabetes? Smoker? Bad family history? HTN? -- all are factors.

Is it ok to have black tea before a cholesterol test?

Cholesterol test: Old answer no, newer answer is maybe. Either ask the lab that is going to do the test or pass on anything other than water before.

Docs, could a cholesterol test tell you if you have diabetes?

Docs, could a cholesterol test tell you if you have diabetes?

Not directly: A blood sugar test is necessary to diagnose diabetes. However, many people with Type 2 diabetes have high triglycerides and low HDL levels, so this might make a doctor suspicious that someone with this pattern on a cholesterol panel might have diabetes.

Could consuming chicken affect my fast for my cholesterol test in the morning?

Any food: Any food can affect your fast. Fasting blood work should only have you drinking water or black coffee. No food.

What can I do if my cholesterol test resulted high: LDL 143.4, HDL 80.5, cholesterol 202, should I get worried?

What can I do if my cholesterol test resulted high: LDL 143.4, HDL 80.5, cholesterol 202, should I get worried?

Depends: Your LDL is little high (risk is increased) but your HDL ("good" cholesterol) is extremely high (risk is reduced). Moreover, your total cholesterol to HDL ratio is 1.75 - this is extremely favorable. If other risk factors are ok (no hx of heart attack, diabetes, non-smoker, normal bp), I would consider this to be highly favorable and certainly would not recommend treatment with medication.

If I drank a good amount of alcohol seven hours before a cholesterol test, are my results basically inaccurate?

If I drank a good amount of alcohol seven hours before a cholesterol test, are my results basically inaccurate?

No: Even a non-fasting specimen is okay for monitoring this important lab parameter. Alcohol doesn't affect it much. If you do drink to excess on a daily basis, you may ruin your liver. It's a miserable way to live and die, but your cholesterol will be low. Otherwise, drink sensibly and enjoy your life. Best wishes.

Dr told me to eat every 3 hrs. Have low blood sgrs around 34. Diabetic on no meds. Cholesterol test soon. Do I fast?

Dr told me to eat every 3 hrs. Have low blood sgrs around 34. Diabetic on no meds. Cholesterol test soon. Do I fast?

Possibly reactive: If you are diabetic but not on medication to treat it, you may be having reactive hypoglycemia. This occurs when the blood sugar rises excessively soon after eating, causing your pancreas to put out Insulin late, resulting in a low sugar about 3 hrs after eating. Rather than eating more frequently, you need to avoid concentrated sweets and carbohydrates that cause the sugar to rise soon after eat.

Hi my mom is going to take a cholesterol test tomorrow. Should she fast, if so how many hours? She didn't ask the dr. Thank you

12 hours: It is good to fast for 12 hours before the test. If she is on medication, she should take the medication and drink water as needed.

Did a cholesterol test & I don't know how to read it & total 144, HDL 35, total/hdl ratio 4.1 is this normal, high or low & BP 120/78?

Did a cholesterol test & I don't know how to read it & total 144, HDL 35, total/hdl ratio 4.1 is this normal, high or low & BP 120/78?

Cholesterol: The levels you report are basically normal. We also usually record the HDL and LDL as these give a bit more information. In someone with minimal or no risk factors an LDL up to 120 may be ok, if risk factors present we prefer 80ish. Hdl of 35 is a bit low.

Would a single chicken nugget affect a cholesterol test? Was fasting for 16 hours and I caved. My levels weren't very high just a bit. Would it raise it?

Would a single chicken nugget affect a cholesterol test? Was fasting for 16 hours and I caved. My levels weren't very high just a bit. Would it raise it?

Not much: If you normally have normal triglycerides and they were a bout the same as usual then the one nugget probably did not have much effect in your LDL those two readings are the ones affected by eating. You more than likely got a good idea of your readings from that test!

Could I use blood from nose bleed for blood or cholesterol test?

Could I use blood from nose bleed for blood or cholesterol test?

Probably not: You can only use it if you are prepared to receive it in the proper type of medium and spin off the serum before it clots.
