Well seem COPD nurse SO was hoping to grill her about blood test had done.
Haematology .. FBC
Biochemistry - Bone, U&E & EGFR, Ferritin, Magnesium, B12/ Folate, Cholesterol, Glucose ( fasting ) LFT, Thuroid Function Test, Vitamin D Metabolites.
To name a few ... i was quit looking forward to results as been so ill SO could start feeling better Reciving treatment if out found .
Only to be delt a blow and told O the computors not working and i cant log on.
Do they know me that well
Like really SO i guess all have to talk about my FEV1 73% that on appearance looks great THAT i surspect is bull really
As i cant see how that can give you good indecation of whats going on in lungs unless its just obstructive restrictive messermeant.
To find out whats going on in our lung am sure we need regular oxygen co2 defusing test.
But we dont GET them often why
Measurement of diffusing capacity of the lungs for carbon monoxide (DLCO), also known as transfer factor, is the second most important pulmonary function test (PFT), after spirometry. Previously available only in hospital-based PFT labs, DLCO testing is now available at outpatient clinics using a portable device. Compared to spirometry tests, assessments with these devices require very little effort. The patient breathes quietly, inhales the test gas, holds the breath for ten seconds, and then exhales. In adult smokers with post-bronchodilator airway obstruction, a low DLCO greatly increases the probability of the emphysema phenotype of COPD due to cigarette smoking, while a normal DLCO makes chronic asthma more likely. In patients with spirometric restriction (a low FVC with a normal FEV1/FVC), a low DLCO increases the pre-test probability of an interstitial lung disease (ILD), while a normal DLCO makes a chest wall type of restriction more likely. A normal TLC (VA from the single-breath helium dilution provided by a DLCO test) rules out restriction of lung volumes without the need for a body box measurement. In patients with dyspnea of unknown cause, the pattern of a low DLCO with normal spirometry increases the likelihood of pulmonary vascular disease, but this pattern also occurs with several other diseases such as a mild ILD. Once a diagnosis is made, the percent predicted DLCO provides an objective index of disease severity and prognosis. A DLCO below 40% predicted, or a decline in DLCO of more than 4 units, is associated with increased morbidity and mortality.
My copd nurse never told me all that a guess thats why spiromity fev is all bit wishy washey when you ask for answers.
