Can a cmp blood test diagnose a disease?

Can a cmp blood test diagnose a disease?

Yes: Complete metabolic panel is usually a screening test but each of the components can provide diagnostic information, e.g., elevated blood glucose could be diagnostic or diabetes.

Comprehensive Metabolic Panel (Definition)

The comprehensive metabolic panel (cmp) is a panel of blood tests that serves as an initial broad medical screening tool. The cmp provides a rough check of kidney function, liver function, and electrolyte and fluid balance. The cmp is an expanded version of the basic metabolic panel (bmp), which does not include liver tests. A cmp (or bmp) is usually ordered as part of ...Read more

What is a CMP blood test? What would the results tell you about someone

CMP: Comprehensive metabolic profile includes your kidney function liver function and electrolyte profile including sodium potassium and a few others.

I have white small stringy particles in urine. No symptoms but scared something is wrong. Did a CMP blood test and all was normal. What could it be?

Urinalysis: A urine examination would have been more useful than a CMP. Do you have any symptoms? Could it be mucus from your genital tract rather than coming from the urinary bladder?
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex.

A cmp blood test says albumin/globulin ratio is 2.6 (says normal range is 1-2.1). What is this ratio, and what do results mean? Should I be concerned?

A cmp blood test says albumin/globulin ratio is 2.6 (says normal range is 1-2.1). What is this ratio, and what do results mean? Should I be concerned?

I wouldn't worry: High albumin doesn't occur except in dehydration which also raises globulin, so your total globulin is a bit low overall. Chances are you're one of the folks who makes less in the way of antibodies than other folks, at least right now. This level's no danger to you. These investigations are seldom productive and if you feel well, I'd simply be thankful for good health and keep an eye on it.

Had a cmp blood test done and my bilirubin was 2.1 and range went up to 1.1. Is this ok? All other liver enzymes were perfect. Should I ask for more?

Had a cmp blood test done and my bilirubin was 2.1 and range went up to 1.1. Is this ok? All other liver enzymes were perfect. Should I ask for more?

Gilbert's? Other?: This is relatively common. You want to fractionate the bilirubin into its direct/conjugated & indirect/conjugated. If it is primarily direct, rule out cholestasis from medicine or dubin-johnson/rotor, with normal alk phos other causes unlikely. If has been up in the past like this and there have been no troubles, it like likely gilbert's non-disease, get a reticulocyte count to r/o hemolysis.

What could cause a urine pH of 5.0 consistently with normal cmp blood test!?

What could cause a urine pH of 5.0 consistently with normal cmp blood test!?

That is normal.: Slightly acidic urine is completely normal. Many of the waste products that kidneys get rid of are acidic, and so urine ph usually is also. Normal urin ph ranges from 5.0 to 8.0, with 7.0 being neutral.

Had blood test cmp and CBC with differential. Their normal so would that rule out celiac desiease?

Had blood test cmp and CBC with differential. Their normal so would that rule out celiac desiease?

Not at all: People with CD can have a stable general medical condition with normal CBC & CBC. To test for CD you look for evidence that your body has formed antibodies to your gut. These include Transglutaminase IgA, Gliadin-transglutaminase IgA complex and others. These are often part of a "celiac panel" performed in a larger or specialty lab. If these are high, referral for confirmatory GI testing is common.

Will nicotine usage be shown on a blood test? The tests they're doing are ferritin, cbc, c-sk and cmp

Will nicotine usage be shown on a blood test? The tests they're doing are ferritin, cbc, c-sk and cmp

No: What is c-sk? It is not a name that I am familiar with. However, none of the other tests are designed to measure nicotine or its metabolites.

24hrs since a CBC, CMP, lipid profile blood test Is there something wrong? Or an emergency that I have to come in?

24hrs since a CBC, CMP, lipid profile blood test Is there something wrong? Or an emergency that I have to come in?

Depends: Depends on the policies of the office. I always ask my patients to come in after multiple blood tests so I can sit down with them and explain what was done and what the tests showed - even normal ones. The biggest complaint patients have is that their doctors don't explain adequately.

I regularly donate blood every 2 months. Would this affect blood test results and so which ones? CBC? LFT? CMP? Tbili?

I regularly donate blood every 2 months. Would this affect blood test results and so which ones? CBC? LFT? CMP? Tbili?

Iron: Serum iron and ferritin levels are likely to be affected before any other test results. Do not wait for hemoglobin to drop. If you donate blood regularly, it would be a good idea to take oral iron supplements.

Can menstrual cycle cause low bun on CMP (7 on range Normal: 8-20) & low Lymphs, Abs on CBC (1 on range Normal: 1.2-3.4)? What does null mean on a blood test? Thank you very much for your time.

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, Your test results do not seem to be a cause for concern. Null=zero

My cmp blood test says TSH w/reflex to f4 is 4.44 miu/l (normal range is 0.4-4.5). Do I have hypothyroidism? I have sparse eyebrows on the outer third

Not likely.: Tsh in "normal" range so not technically hypothyroid. Some would argue that TSH should actually be lower. I would repeat this in a few months. If normal again would stop worrying. If abnormal diagnosis is clear. In any case eyebrow thinning is not likely due to this tsh.

Is my psychiatrist in the position to demand a blood panel 9? And would the drug appear in urine test or blood test she wrote CBC deff/tsh cmp uds 9

Is my psychiatrist in the position to demand a blood panel 9? And would the drug appear in urine test or blood test she wrote CBC deff/tsh cmp uds 9

Lab work: The doctor ordered CBC with differential (which is blood cells count with count of different cell classes) TSH (which is thyroid stimulating hormone) cmp (which is comprehensive metabolic panel) uds 9 (which is urine drug screen 9-drug panel). All those are routine orders and any psychiatrist would need to know the results to properly assess a patient. There is no reason to suspect of your doctor.

If I have a blood test tomorrow morning and I smoked marijuana tonight would it show up? They're testing hemoglobin, mono, tsh, lyme, cmp, sed rate

If I have a blood test tomorrow morning and I smoked marijuana tonight would it show up? They're testing hemoglobin, mono, tsh, lyme, cmp, sed rate

Probably not: Most drug screening tests are urinalysis. Although blood tests can be done they are much more expensive. It sounds like your labs have been ordered to work up specific symptoms, to better help you physician make a clinical diagnosis. I am very skeptical that a thc level would be included in this type of workup. Hopefully you live in a pot legal state.....Otherwise be careful!

I had a blood test (cbc w/diff, cmp, lipid, thyroid). All were normal (other than slightly low RDW & cholesterol). Feel exhausted often. What next?

I had a blood test (cbc w/diff, cmp, lipid, thyroid). All were normal (other than slightly low RDW & cholesterol). Feel exhausted often. What next?

Further evaluation: There are many common causes of fatigue that have not yet been ruled out. You likely did not get adequate thyroid tests. You might have chronic infections such as lyme disease or viral infections, intestinal parasites, heavy metal toxicity, mold toxicity, corticoadrenal insufficiency, depression, vitamin or mineral deficiencies, sleep apnea, food sensitivities etc. Please see my comment:.

I think I have a stomach virus and I am scheduled for a blood test tomorrow morning (fasting lipid panel, CMP w/EGFR, CPK, PSA). Should I postpone?

I think I have a stomach virus and I am scheduled for a blood test tomorrow morning (fasting lipid panel, CMP w/EGFR, CPK, PSA). Should I postpone?

Should not impact: The tests you listed are not likely to change if not feeling well. Consider the phlebotomist, though and postpone if actively symptomatic so you don't transmit it.
