Thyroid blood test indicators

Many people have done thyroid blood tests on a regular basis. This examination indicator needs to be judged based on the results of the examination. There is no way to make a reasonable summary because everyone's physical condition is different. The thyroid can be divided into several different examination stages. The first is to perform touch diagnosis and accurate testing, and then analyze the current situation based on the condition. Corresponding blood tests are to prevent the condition from worsening.

1. Inspection method : Observe the size and symmetry of the thyroid gland. In normal people, the thyroid gland does not appear prominent, but may slightly increase in size during puberty in women. During the examination, ask the person being examined to swallow. It can be seen that the thyroid gland moves upward with the swallowing movement. If it is difficult to identify, ask the person being examined to put both hands behind the pillow and tilt the head back. Then observe again and it will be more obvious.

(ii) Palpation (1) Isthmus of the thyroid gland: The isthmus of the thyroid gland is located below the cricoid cartilage and in front of the second to fourth tracheal rings. Stand in front of the subject and touch upward from the suprasternal notch with your thumb, or stand behind the subject and touch with your index finger. You can feel the soft tissue in front of the trachea to determine whether it is thickened. Ask the subject to swallow. You can feel the soft tissue sliding under your fingers to determine whether it is enlarged or lumpy. (2) Lateral lobe of the thyroid: Palpation from the front: Use the thumb of one hand to apply pressure to the thyroid cartilage on one side to push the trachea to the opposite side. Use the index and middle fingers of the other hand to push the lateral lobe of the thyroid forward along the posterior edge of the sternocleidomastoid muscle on the opposite side. Use the thumb to palpate the anterior edge of the sternocleidomastoid muscle. Repeat the examination while swallowing. The pushed thyroid gland can be felt. Check the other thyroid gland in the same way. Posterior palpation: Similar to anterior palpation. The index and middle fingers of one hand apply pressure to the thyroid cartilage on one side to push the trachea to the opposite side. The thumb of the other hand pushes the thyroid gland forward at the posterior edge of the opposite sternocleidomastoid muscle, and the index and middle fingers palpate the thyroid gland at its front edge. Coordinate swallowing and repeat the check. Check the other thyroid gland in the same way.

(III) Auscultation: When you feel an enlarged thyroid gland, place a bell-shaped stethoscope directly on the enlarged thyroid gland. If you hear a low-pitched, continuous venous "buzzing" sound, it is very helpful in diagnosing hyperthyroidism. In addition, systolic arterial murmurs may be heard in patients with diffuse goiter and hyperfunction.

(IV) Thyroid enlargement can be divided into three degrees: Grade I is when the enlargement cannot be seen but can be felt; Grade II is when the enlargement can be seen and felt but is within the sternocleidomastoid muscle; and Grade III is when the enlargement exceeds the outer edge of the sternocleidomastoid muscle.

Thyroid experiment Thyroid: Section No. 55, pig or cat thyroid and parathyroid, HE staining.

Capsule: It is composed of connective tissue, extends into the substance and divides the substance into many lobules.

Alveoli: round or oval, the alveolar cavity contains pink gelatinous substance. The alveolar epithelium is a simple cuboidal epithelium. There are cells with clear cytoplasm, sandwiched between the alveolar epithelium and the basement membrane. There is a larger type of cell called paraacinar cells.
