What Does A Low T4 Level Mean
It can mean: An elevated level of thyroid hormone, either due to hyperthyroidism or thyroid inflammation. It can be falsely elevated by estrogen therapy. Other thyroid tests are more reliable. The T3 (liothyronine) you're receiving is potentially dangerous and should not be taken. It can not me measured in the blood and has potential toxicity. Use brand name T4 only if replacement is required, . ...Read more
Immunodeficiency: Immunoglobulin g, igg, is an antibody, a protein that the immune system makes to help fight infection. Igg floats around in the blood stream and helps fight bacteria and viruses. An igg level of 3 is exceedingly low. In most labs, a normal igg level is around 700. Low igg can predispose you to having recurrent infections. You should see an immunologist about igg replacement. ...Read more
IgA deficiency is: the most common of all the "selective antibody deficiencies " occurring in 1:300-1:700 of the population. Levels vary greatly from person to person and in different age groups. Infants have the lowest range of normal and sometimes IgA is either extremely low or may be undetectable in the newborn period. Levels are typically checked if someone has recurring infections of the sinuses, ears or lung ...Read more
Need to look at T3 (liothyronine): And free t4. Low tsh, depending on the sensitivity of the assay, indicates thyroid hyper-function. However, the suspected hyperthyroidism needs to be confirmed with high levels of T3 (liothyronine) and free t4. All lab tests need to be evaluated in the clinical context and it would be prudent to take up the issue with your doctor. ...Read more
Nothing bad: Iga is the amount of immunoglobulin a and it can be measured in the blood serum and less commonly in the saliva. While a low amount of serum IgA may predispose some people to recurrent infections, an elevated serum IgA is nothing to worry about. It means the person is making good amounts of antibody. ...Read more
Immune test: The body normally makes immunoglobulins iga, igg, igm, ige and igd. Low or absent IG levels are seen in patients with recurrent infections. A low igm level that is clinically relevant usually occurs in the presence of a low igg and/or IgA level. It is always best to treat a patient, not a number. If a person is otherwise healthy and only has lower igm, usually no worries. ...Read more
It depends: There are several types of immunoglobulin, igg, iga, IgM and ige. Having a "high" level of each of them could mean different things. It is also important to know if it is a "high" overall level, or a "high" level of a specific kind of igg, iga, igm, or ige. In general, a high ige means "allergy". High igg/a/m can mean different things depending on their specificity (total or specific). ...Read more
Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level if you have symptoms it would be wise to seek treatment. ...Read more
Maybe nothing?: Igm is a type of antibody you make to help fight infections. Slightly low igm by itself may not mean anything (i.e., your nature level). If it is very low, or other antibodies are also low (or not functioning), it may be a sign of immune deficiency that can lead to more infections. If you have ?S, see a clinical immunologist. They can help determine if your immune system is functioning properly. ...Read more
Need proper testing: Probably refers to TSH slightly abnormal. However here is hoe to be sure: check free T3 and reverse t3. Ft3 should be in upper range and rt3 in lower range. If your ratio is off, you may need Armour Thyroid or t3, and synthroid (thyroxine) would be the wrong med for you. ...Read more
More workup: Currently, it points to hyperthyroidism but you need to complete the work up to know for sure. At the very least, i would repeat the TSH along with the free hormones T4 and t3 (liothyronine). If they also point to hyperthyroidism, then proceed further to find the exact cause for this. Tsh alone does not give you a complete picture. ...Read more
Lymphocytosis: Lymphocytosis is is an increase in white blood cells called lymphocytes. Usually the number is temporary rise in the number of lymphocytes after an infection. White blood cells are an important part of the immune system. ...Read more
