- Overview & Description. This test is used to determine the amount of bicarbonate, called HCO3, in the blood. The test actually measures the blood level of carbon dioxide, called CO2. During laboratory testing, HCO3 is converted to CO2. HCO3 is important in neutralizing acids.he normal value for CO2 in the blood is 23 to 29 mEq/L. Most of the carbon dioxide in the blood is in the form of bicarbonate. Either term can be used.

What Are Normal HCT and Hgb Levels? Quick Answer. Normal HCT, or hematocrit, levels are 38.8 to 50 percent for men and 34.9 to 44.5 percent for women, according to Mayo Clinic. For hemoglobin, or Hgb, tests, normal results are 12 to 15.5 grams per deciliter for women and 13.5 to 17.5 for men.

Respiratory acidosis In chronic respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range, with a normal blood pH (7.35 to 7.45) or near-normal pH secondary to renal compensation and an elevated serum bicarbonate (HCO3− >30 mm Hg).

- Person pH is in normal range PCO2 is low (acid) and PCO2 is the respiratory component HCO3- is high (alkalosis) and HCO3- is the metabolic component When the PCO2 and HCO3- are both out of range but the pH is within range the person had a problem but has fully compensated for it.f the compensation is partial the pH will still be out of range, if it is fully compensated the PCO2 and HCO3- will both be out of range but the pH will within range. EXAMPLE ONE DATA pH = 7.31 PCO2 = 52 HCO3- =28 Step one: Is the pH Normal, Acid, or Alkaline?

Thyroid Function Tests T3 tests, which check for levels of triiodothyronine, are usually ordered if T4 tests and TSH tests suggest hyperthyroidism. The T3 test may also be ordered if you are showing signs of an overactive thyroid gland. The normal range for the T3 is 100-200 nanograms of hormone per deciliter of blood.rawing Blood for Thyroid Function Tests. Talk to your doctor about any medications you are taking and tell your doctor if you are pregnant. Certain medications and pregnancy may influence your test results. A blood draw, also known as venipuncture, is an outpatient procedure performed at a lab or a doctor’s office.

Enbrel These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider. Results are given in milliequivalents per liter (mEq/L). Normal results range from 25 to 40 mEq/L. If your levels are below 25 mEq/L, you may have a lack of chloride in your diet. It may also mean that you have been vomiting or had medical suctioning of your stomach contents. It may also mean that you have used diuretics in the past.

Low T4 and T3 but Normal TSH The thyroid fiction tests are also compatible with renal insufficiency and this is the reason I asked for creatinine and/or BUN values. The borderline low T4 and T3 with normal TSH, slightly low TBG and slightly high PRL are typical. TBG abnormality is also a possibility, although free T4 should be normal.However if the defect is inherited and results in a mutant TBG with lower affinity for T4 and T3, rather than low amount of TBG, measurement of free T4 by direct method my give a spurious value.he thyroid fiction tests are also compatible with renal insufficiency and this is the reason I asked for creatinine and/or BUN values.

The pattern of liver test abnormality is hepatocellular. The AST is typically in the 100 to 200 IU/L range, even in severe disease, and the ALT level may be normal, even in severe cases. The AST level is higher than the ALT level, and the ratio is greater than 2:1 in 70% of patients.

- RENAL BUFFER RESPONSE  In an effort to maintain the ph of blood within its normal range, the kidneys excrete or retain bicarbonate. As the blood ph decreases, the kidney will compensate by retaining HC03 and as the ph rises, the kidneys excrete HC03 through the urine.Compensation of the kidneys takes from hours to days. RESPIRATORY ACIDOSIS  Respiratory acidosis is defined as a ph less than 7.35 with a PC02 greater than 45 mmhg.ENAL BUFFER RESPONSE  In an effort to maintain the ph of blood within its normal range, the kidneys excrete or retain bicarbonate.

- 1 In plasma, the normal ratio of bicarbonate (HCO3-) to carbonic acid (H2CO3) is 20:1. 2  This ratio keeps the blood pH level within the normal range of 7.35 to 7.45. 3  Blood pH becomes more alkaline as the ratio increases (for example, 22:1). pH of 7 is neutral, below 7 is acidic, and above 7 is basic. The pH is defined as the negative logarithm, to the base 10, of the H+ concentration. o pH = -log10[H+]. The normal pH of arterial blood is 7.35 to 7.45.

- 1 The kidney filters approximately 4320 meq/day of HCO3- (24 meq/L × 180L/day). 2  Under normal circumstances, the kidney is able to completely reabsorb all the filtered bicarbonate. 3  This is vitally important, since any loss of bicarbonate in the urine would disturb acid base balance.

Patient Education 2 Understanding your complete blood count  Hematocrit (HCT) value The hematocrit value measures how much of your total blood count is made up of red blood cells.The normal range for HCT is 36 to 52%.he normal range for WBC is 5 to 10 K/uL. Your CBC will also measure what’s called the ANC (absolute neutrophil count) That’s the specific number of white blood cells in your blood that fight infection.  Red blood cell (RBC) count Red blood cells carry oxygen and remove waste from your body.

Base Excess / Base Deficit Calculation of the base excess or deficit is a way of quantifying HCO 3 - . Base excess is the quantity of base (HCO 3 - , in mEq/L) that is above or below the normal range of buffer base in the body (22 -28 mEq/L). This cannot be calculated from PCO 2 and pH as the hemoglobin also contributes to the buffer base. One can use the Siggaard-Andersen nomogram to estimate base excess or deficit.

- Sodium bicarbonate administration: It is recommended that 50% of total deficit be given over 3 to 4 hours, and the remainder replaced over 8-24 hours. The usual initial target ((desired HCO3- concentration): 10 - 12 mEq/L, which should bring the blood pH to ~7.20.
